| MOOS-IvP uMemWatch through 24.8.1 constructs shell commands from attacker-chosen MOOS client names without sanitization. Attackers can inject shell metacharacters into client names to execute arbitrary commands as the uMemWatch process user through unquoted redirection targets in system calls. |
| A vulnerability was found in D-Link DNS-340L 1.01B04. Affected by this issue is some unknown functionality of the file /cgi-bin/dropbox.cgi of the component CGI Handler. Performing a manipulation of the argument callback_url/sync_interval results in os command injection. The attack can be initiated remotely. The exploit has been made public and could be used. |
| Dell SmartFabric OS10 Software, versions prior to 10.5.6.14, contains an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Command execution. |
| Authenticated command injection vulnerabilities exist in the command line interface of AOS-CX. Successful exploitation of these vulnerabilities results in the ability to execute arbitrary commands as a privileged user on the underlying operating system. |
| In the Linux kernel, the following vulnerability has been resolved:
udf: validate sparing table length as an entry count, not a byte count
udf_load_sparable_map() accepts a sparing table when
sizeof(*st) + le16_to_cpu(st->reallocationTableLen) > sb->s_blocksize
is false, i.e. it treats reallocationTableLen as a number of BYTES that
must fit in the block. But the table is walked as an array of 8-byte
sparingEntry elements:
for (i = 0; i < le16_to_cpu(st->reallocationTableLen); i++) {
struct sparingEntry *entry = &st->mapEntry[i];
... entry->origLocation ...
}
in udf_get_pblock_spar15() and udf_relocate_blocks(). A
reallocationTableLen of N therefore passes the check whenever
sizeof(*st) + N <= blocksize, yet the consumers index
sizeof(*st) + N * sizeof(struct sparingEntry) bytes -- up to ~8x the
block. On a crafted UDF image this is an out-of-bounds read in
udf_get_pblock_spar15(); udf_relocate_blocks() additionally feeds the
same length to udf_update_tag(), whose crc_itu_t() reads far past the
block, and its memmove() through st->mapEntry[] is an out-of-bounds
write.
Validate reallocationTableLen as the entry count it is, with
struct_size(). |
| In the Linux kernel, the following vulnerability has been resolved:
udf: validate VAT header length against the VAT inode size
udf_load_vat() takes the virtual partition's start offset straight from
the on-disk VAT 2.0 header without checking it against the VAT inode
size:
map->s_type_specific.s_virtual.s_start_offset =
le16_to_cpu(vat20->lengthHeader);
map->s_type_specific.s_virtual.s_num_entries =
(sbi->s_vat_inode->i_size -
map->s_type_specific.s_virtual.s_start_offset) >> 2;
lengthHeader is a fully attacker-controlled 16-bit value. If it exceeds
the VAT inode size, the s_num_entries subtraction underflows to a huge
count, which defeats the "block > s_num_entries" bound in
udf_get_pblock_virt15(); and on the ICB-inline path that function reads
((__le32 *)(iinfo->i_data + s_start_offset))[block]
so a large s_start_offset indexes past the inode's in-ICB data. Mounting
a crafted UDF image with a virtual (VAT) partition then triggers an
out-of-bounds read.
Reject a VAT whose header length does not leave room for at least one
entry within the VAT inode. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Validate BTF repeated field counts before expansion
btf_parse_struct_metas() walks user-supplied BTF during BPF_BTF_LOAD,
and btf_repeat_fields() expands repeatable fields from array elements
into the fixed BTF_FIELDS_MAX scratch array used by btf_parse_fields().
The remaining-capacity check performs the expanded field count calculation
in u32. A malformed BTF can wrap that calculation, causing the check to
pass even when the expanded field count exceeds the scratch array
capacity. The following memcpy() can then write past the end of the
array.
Use checked addition and multiplication before copying repeated fields
and reject impossible counts. |
| A maliciously crafted PDF file, when parsed through Autodesk Revit, can force an Out-of-Bounds Write vulnerability. A malicious actor may leverage this vulnerability to cause a crash, cause data corruption, or execute arbitrary code in the context of the current process. |
| A flaw was found in GDB's STABS debug format parser. The
read_member_functions() function in gdb/stabsread.c contains a linked
list removal bug in the code that separates destructor and non-destructor
member functions of C++ classes. The bug causes the destructor entries to
remain in the main function list while the list length counter is
decremented, resulting in an out-of-bounds write when the function list
is copied to its final allocated array. An attacker can craft an ELF
binary with malicious .stab and .stabstr sections that triggers this
out-of-bounds write when a user opens the file in GDB and performs any
symbol-inspection operation such as setting a breakpoint. The inferior
process does not need to be executed. Under controlled conditions, this
was demonstrated to achieve execution of arbitrary commands within the
GDB process. |
| A vulnerability has been found in D-Link DNS-340L 1.01B04. Affected by this vulnerability is an unknown functionality of the file /cgi-bin/addon_center.cgi of the component Add-On Center. Such manipulation of the argument f_name/f_url/f_flag/f_login_user leads to os command injection. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. |
| Memory Allocation with Excessive Size Value (CWE-789) in the Prometheus remote_write HTTP handler in Metricbeat can lead Denial of Service via Excessive Allocation (CAPEC-130). |
| shell-quote's `quote()` function did not validate object-token inputs against the operator model used by `parse()`. The `.op` field was backslash-escaped character by character using `/(.)/g`, which in JavaScript does not match line terminators (\n, \r, U+2028, U+2029). A line terminator in `.op` therefore passed through unescaped into the output; POSIX shells treat a literal newline as a command separator, so any content after it would execute as a second command. The vulnerable code path is reachable in two ways: (1) direct construction of `{ op: '...\n...' }` from external input, and (2) via `parse(cmd, envFn)` when `envFn` returns object tokens whose `.op` is attacker-influenced. Both are documented API surface. Fixed by replacing the per-character escape with strict shape validation: `.op` must match the parser's control-operator allowlist; `{ op: 'glob', pattern }` validates `pattern` and forbids line terminators; `{ comment }` validates `comment` and forbids line terminators; any other object shape throws `TypeError`. |
| In the Linux kernel, the following vulnerability has been resolved:
dm log: fix out-of-bounds write due to region_count overflow
The local variable region_count in create_log_context() is declared as
unsigned int (32-bit), but dm_sector_div_up() returns sector_t (64-bit).
When a device-mapper target has a sufficiently large ti->len with a small
region_size, the division result can exceed UINT_MAX. The truncated
value is then used to calculate bitset_size, causing clean_bits,
sync_bits, and recovering_bits to be allocated far smaller than needed
for the actual number of regions.
Subsequent log operations (log_set_bit, log_clear_bit, log_test_bit) use
region indices derived from the full untruncated region space, causing
out-of-bounds writes to kernel heap memory allocated by vmalloc.
This can be reproduced by creating a mirror target whose region_count
overflows 32 bits:
dmsetup create bigzero --table '0 8589934594 zero'
dmsetup create mymirror --table '0 8589934594 mirror \
core 2 2 nosync 2 /dev/mapper/bigzero 0 \
/dev/mapper/bigzero 0'
The status output confirms the truncation (sync_count=1 instead of
4294967297, because 0x100000001 was truncated to 1):
$ dmsetup status mymirror
0 8589934594 mirror 2 254:1 254:1 1/4294967297 ...
This leads to a kernel crash in core_in_sync:
BUG: scheduling while atomic: (udev-worker)/9150/0x00000000
RIP: 0010:core_in_sync+0x14/0x30 [dm_log]
CR2: 0000000000000008
Fixing recursive fault but reboot is needed!
Fix by widening the local region_count to sector_t and adding an
explicit overflow check before the value is assigned to lc->region_count. |
| Vim is an open source, command line text editor. Prior to version 9.2.0276, a modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file. The `complete`, `guitabtooltip` and `printheader` options are missing the `P_MLE` flag, allowing a modeline to be executed. Additionally, the `mapset()` function lacks a `check_secure()` call, allowing it to be abused from sandboxed expressions. Commit 9.2.0276 fixes the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: loongson2: Fix sg iteration in data reorder functions
In ls2k0500_mmc_reorder_cmd_data() and ls2k2000_mmc_reorder_cmd_data(),
the for_each_sg() macro already iterates over the scatterlist entries,
with 'sg' pointing to the current entry. However, the code incorrectly
uses '&sg[i]' and 'sg_dma_len(&sg[i])' inside the loop, which treats
'sg' as an array base and indexes it again, leading to access of
wrong sg entries (or out-of-bounds if the list is not an array). |
| In the Linux kernel, the following vulnerability has been resolved:
net: gro: properly validate BIG TCP aggregation criteria
When GRO attempts to aggregate packets beyond GRO_LEGACY_MAX_SIZE (64KB),
BIG TCP should only be permitted for plain IPv4 TCP and plain IPv6 TCP
(with sufficient MAC header room to insert the temporary HBH jumbo header).
However, commit b1a78b9b9886 ("net: add support for ipv4 big tcp")
loosened the check in skb_gro_receive(), leading to several issues:
1. skb_gro_receive() checked skb_headroom(p) instead of the actual space
before the MAC header (p->mac_header). Because skb_headroom(p) includes
mac_len, crafted frames (e.g. injected via AF_PACKET) can pass the check
with p->mac_header < 8 bytes. When ipv6_gro_complete() inserts the
temporary HBH jumbo header, the memmove() starts before skb->head,
causing an out-of-bounds write and wrapping skb->mac_header.
2. It allowed non-IP protocols such as software VLAN (ETH_P_8021Q /
ETH_P_8021AD) to aggregate beyond 64KB because
p->protocol != ETH_P_IPV6 was true.
3. It checked p->encapsulation instead of NAPI_GRO_CB(skb)->encap_mark,
allowing encapsulated flows (e.g. SIT / IPv6-in-IPv4) to aggregate
beyond 64KB.
Fix skb_gro_receive() to strictly enforce:
- NAPI_GRO_CB(skb)->proto == IPPROTO_TCP
- Not encapsulated (!NAPI_GRO_CB(skb)->encap_mark && !p->encapsulation)
- Protocol must be either ETH_P_IP or ETH_P_IPV6
- If ETH_P_IPV6, p->mac_header must be at least
sizeof(struct hop_jumbo_hdr)
Returning -E2BIG from skb_gro_receive() ensures that packets which cannot
become BIG TCP are cleanly flushed at <= 64KB and delivered intact without
dropping.
This issue does not exist in mainline (7.0+) because the subsystem was
rewritten in commit 81be30c1f5f2 ("net/ipv6: Drop HBH for BIG TCP on RX
side"), making this fix relevant only for older stable branches like
6.18.y. |
| PX4 Autopilot contains a heap buffer overflow vulnerability in the sd_bench command that writes a four-byte block number into a user-supplied sized allocation. Attackers can invoke sd_bench with a block size below four bytes to overflow the heap buffer and potentially execute code or crash the system. |
| Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.17.4, on the Nuclio local Docker platform, the function namespace is interpolated—unvalidated—into a double-quoted docker ps --filter "label=nuclio.io/namespace=<value>" command that is executed via the host shell (/bin/sh -c). Because the default auth kind is nop (unauthenticated), a remote attacker can inject arbitrary OS commands that run as root inside the dashboard container, which holds the Docker socket → host compromise. This issue has been patched in version 1.17.4. |
| A flaw was found in rpm. A local attacker could supply a specially crafted `.gem` filename containing RPM macro syntax. When a user or automated workflow invokes `rpmuncompress -x` on this file, the macro expansion occurs during command construction. This allows the attacker to execute arbitrary commands with the privileges of the invoking account, leading to a compromise of confidentiality, integrity, and availability. |
| LibreNMS versions >= 23.10.0 and < 26.2.0 (fixed in 26.4.0) contain an authenticated OS command injection vulnerability in libvirt discovery. When libvirt support is enabled (enable_libvirt=true), the device hostname ($this->getDevice()->hostname) is concatenated into shell commands (ssh, virsh list/dumpxml/domstate) in VminfoLibvirt.php and passed to exec() without escapeshellarg() or argument separation. An authenticated admin can set a crafted device hostname to inject arbitrary OS commands, leading to remote code execution in the discovery worker context. |
