1) Heap-based buffer overflow (CVE-ID: CVE-2022-24834)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the cjson and cmsgpack libraries. A remote attacker can trick the victim into using a specially crafted Lua script to trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


2) Heap-based buffer overflow (CVE-ID: CVE-2023-36824)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error when extracting key names from a command and a list of arguments. A local user can execute the "COMMAND GETKEYS" or "COMMAND GETKEYSANDFLAGS" commands or execute a specially crafted command that refers to a variadic list of key names along with ACL rules that match key names to trigger a heap-based buffer overflow and execute arbitrary code on the target system.
