Symlink-based path traversal in the Perl module Archive::Tar before version 3.08 allows a malicious tar archive to write or point files outside the intended extraction directory. When an application extracts an attacker-supplied archive, symlink entries whose targets are absolute paths or contain '..' traversal sequences are followed without validation, letting an attacker place links that resolve to arbitrary filesystem locations. EPSS is very low (0.02%, 6th percentile) and there is no public exploit identified at time of analysis, but the issue is rated CVSS 9.1 because Archive::Tar is widely embedded in automated server-side processing of untrusted archives.
Memory exhaustion in the Perl Archive::Tar module before version 3.10 lets remote attackers cause a denial of service by supplying a crafted tar archive whose per-entry header declares an arbitrarily large size, which the module trusts and uses to drive allocation before reading. The flaw is unauthenticated and network-reachable (CVSS 7.5, A:H only - no confidentiality or integrity impact) but affects only applications that parse untrusted tarballs with this module. There is no public exploit identified at time of analysis and EPSS is very low (0.02%, 4th percentile); the vendor shipped a fix in 3.10.
Arbitrary file modification in the Perl Archive::Tar module before version 3.08 allows a malicious tar archive to create hardlinks pointing outside the extraction directory. Any application or service that extracts attacker-supplied tarballs is affected: because extraction chmods the shared inode of a hardlink, an attacker can alter permissions of sensitive files outside the intended target path. EPSS is very low (0.02%, 5th percentile) and there is no public exploit identified at time of analysis; it is not listed in CISA KEV.
An issue in Archive v3.3.7 allows attackers to execute a path traversal via extracting a crafted zip file. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
An issue in Archive v3.3.7 allows attackers to spoof zip filenames which can lead to inconsistent filename parsing. Rated high severity (CVSS 7.8), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink. Rated high severity (CVSS 7.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. Public exploit code available.
