Summary

The APT package management tool, specifically versions prior to 1.4.8, exhibits a critical flaw due to improper sanitization of the 302 redirect field in its HTTP transport method. This oversight can be exploited by a man-in-the-middle (MITM) attacker, enabling them to inject malicious content into the communications. Such an attack could ultimately result in unauthorized remote code execution on the target system, compromising its security and integrity. Users of affected versions should apply relevant patches and updates promptly to mitigate any risks associated with this vulnerability.

Affected Version(s)

apt as used in Debian Stretch and Ubuntu 1.4.8 and earlier

Exploit Proof of Concept (PoC)
