2) Heap-based buffer overflow
EUVDB-ID: #VU62830
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-24903
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service or potentially execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when parsing data in imtcp, imptcp, imgssapi, and imhttp modules used for TCP syslog reception. A remote attacker can pass specially crafted data to the application, trigger heap-based buffer overflow and cause a denial of service or potentially execute arbitrary code on the target system.
Successful exploitation of this vulnerability is possible if the attacker is able to directly send specially crafted messages to the rsyslog daemon or by injecting specially crafted data into log files. Vulnerability exploitation in the second scenario requires that the rsyslog client supports octet-counted framing, which is not a default configuration.
