NVD-CWE-OtherPublished: March 8, 2002· Updated: Jun 16, 2026
Official Description
Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service (core dump) and possibly execute arbitrary code with an ftp:// URL with a larger number of special characters, which exceed the buffer when Squid URL-escapes the characters.
Technical Analysis
CVE-2002-0068 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2002-0068. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
