Engrampa is an archive manager for the MATE environment.
Engrampa, the archive manager for the MATE environment, contains a Path Traversal vulnerability in its handling of CPIO archives. This flaw allows crafted archives to cause arbitrary file writes to unintended locations by following symlinks without proper validation. Exploiting this can lead to full Remote Command Execution (RCE) when a victim extracts a malicious archive. The vulnerability was fixed in commit 63d5dfa.
AI Analysis
Technical Summary
Engrampa's archive extraction process for CPIO archives follows stored symlinks by default without verifying their target locations. This behavior enables an attacker to craft malicious CPIO or ISO archives that exploit path traversal to write files arbitrarily on the victim's system. When such an archive is extracted, it can lead to full Remote Command Execution (RCE). The issue was addressed and fixed in commit 63d5dfa.
Potential Impact
Successful exploitation allows an attacker to achieve full Remote Command Execution on the target system by leveraging arbitrary file writes through path traversal in archive extraction. This compromises system integrity and confidentiality, potentially allowing complete control over the affected host.
Mitigation Recommendations
A fix for this vulnerability is available and was implemented in commit 63d5dfa. Users and administrators should update Engrampa to a version that includes this fix to mitigate the risk of exploitation.
