Authorization Bypass

squid is vulnerable to authorization bypass. When handling a URN request, the corresponding HTTP request that is made does not go through the access checks, allowing an attacker to bypass access checks and gain access to restricted HTTP servers such as HTTP servers listening on localhost...

Arbitrary Code Execution

squid is vulnerable to arbitrary code execution. The vulnerability exists as a heap-based buffer overflow could occur when receiving data from a remote server in response to an URN request, and when squid fails to ensure that the response can fit within the buffer...

Internet Bug Bounty: URN Request bypass ACL Checks

Summary: Attacker can bypass ACL checks gaining access to restricted HTTP servers such as those running on localhost. Attacker could also gain access to CacheManager if VIA header is turned off. Only lines with : will be readable though, and the response must be less than 4096 bytes or it'll...

Internet Bug Bounty: UrnState Heap Overflow

Summary: When handling a URN Request an attacker controlled response can cause Squid to overflow a heap buffer. The buffer exist within a struct so not only does it allow an attacker to overflow adjacent memory, but also control a pointer that follows the buffer enabling them to free arbitrary...
