Improper Restriction of Operations within the Bounds of a Memory Buffer

An improper restriction of operations within the bounds of a memory buffer in the MAC address parser of the Zyxel VMG8825-T50K firmware versions through 5.50(ABOM.8)C0 could allow an authenticated attacker with administrator privileges to cause potential memory corruptions, resulting in a thread crash on an affected device.Show less

Envoy is a cloud-native high-performance edge/middle/service proxy. Envoy will crash when the http async client is handling `sendLocalReply` under some circumstance, e.g., websocket upgrade, and requests mirroring. The http async client will crash during the `sendLocalReply()` in http async client, one reason is http async client is duplicating the status code, another one is the destroy of router is called at the destructor of the async stream, while the stream is deferred deleted at first. There will be problems that the stream decoder is destroyed but its reference is called in `router.onDestroy()`, causing segment fault. This will impact ext_authz if the `upgrade` and `connection` header are allowed, and request mirrorring. This issue has been addressed in versions 1.31.2, 1.30.6, 1.29.9, and 1.28.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.Show less

Envoy is a cloud-native high-performance edge/middle/service proxy. Jwt filter will lead to an Envoy crash when clear route cache with remote JWKs. In the following case: 1. remote JWKs are used, which requires async header processing; 2. clear_route_cache is enabled on the provider; 3. header operations are enabled in JWT filter, e.g. header to claims feature; 4. the routing table is configured in a way that the JWT header operations modify requests to not match any route. When these conditions are met, a crash is triggered in the upstream code due to nullptr reference conversion from route(). The root cause is the ordering of continueDecoding and clearRouteCache. This issue has been addressed in versions 1.31.2, 1.30.6, and 1.29.9. Users are advised to upgrade. There are no known workarounds for this vulnerability.Show less

An issue was discovered in WibuKey64.sys in WIBU-SYSTEMS WibuKey before v6.70 and fixed in v.6.70. An improper bounds check allows crafted packets to cause an arbitrary address write, resulting in kernel memory corruption.Show less

Dell Precision Rack, 14G Intel BIOS versions prior to 2.22.2, contains an Access of Memory Location After End of Buffer vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Information disclosure.Show less

A vulnerability, which was classified as critical, was found in TOTOLINK AC1200 T8 and AC1200 T10 4.1.5cu.861_B20230220/4.1.8cu.5207. This affects the function setParentalRules of the file /cgi-bin/cstecgi.cgi. The manipulation of the argument desc/week/sTime/eTime leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. Other parameters might be affected as well. The vendor was contacted early about this disclosure but did not respond in any way.Show less

An issue was discovered in UCI IDOL 2 (aka uciIDOL or IDOL2) through 2.12. Due to improper input validation, improper deserialization, and improper restriction of operations within the bounds of a memory buffer, IDOL2 is vulnerable to Denial-of-Service (DoS) attacks and possibly remote code execution via the \xB0\x00\x3c byte sequence.Show less

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix crash due to incorrect copy_map_value When both bpf_spin_lock and bpf_timer are present in a BPF map value, copy_map_value needs to skirt both objects when copying a value into and out of the map. However, the current code does not set both s_off and t_off in copy_map_value, which leads to a crash when e.g. bpf_spin_lock is placed in map value with bpf_timer, as bpf_map_update_elem call will be able to overwrite the other timer object. When the issue is not fixed, an overwriting can produce the following splat: [root@(none) bpf]# ./test_progs -t timer_crash [ 15.930339] bpf_testmod: loading out-of-tree module taints kernel.

Autel MaxiCharger AC Elite Business C50 AppAuthenExchangeRandomNum Stack-Based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Business C50 EV chargers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the AppAuthenExchangeRandomNum BLE command. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-23384.Show less
