HIGH KEV RANSOMWARE

UnRAR Path Traversal (CVE-2022-30333)

Title source: metasploit
STIX 2.1

Exploitation Summary

CVE-2022-30333 is actively exploited and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, added August 9, 2022, with confirmed use in ransomware campaigns. EIP tracks 7 public exploits from researchers including rbowes-r7, TheL1ghtVn, aslitsecurity, including a Metasploit module exploits/linux/http/zimbra_unrar_cve_2022_30333.

AI-analyzed exploit summary This PoC exploits CVE-2022-30333, a path traversal vulnerability in unRAR versions prior to 6.11, by generating a malicious RAR archive that extracts files to arbitrary locations. The script constructs a RAR file with a symlink and payload data, enabling arbitrary file write during extraction.

Description

RARLAB UnRAR before 6.12 on Linux and UNIX allows directory traversal to write to files during an extract (aka unpack) operation, as demonstrated by creating a ~/.ssh/authorized_keys file. NOTE: WinRAR and Android RAR are unaffected.
