Summary

An issue was discovered in Squid 2.x through 2.7.STABLE9, 3.x through 3.5.28, and 4.x through 4.7. When Squid is configured to use Basic Authentication, the Proxy-Authorization header is parsed via uudecode. uudecode determines how many bytes will be decoded by iterating over the input and checking its table. The length is then used to start decoding the string. There are no checks to ensure that the length it calculates isn't greater than the input buffer. This leads to adjacent memory being decoded as well. An attacker would not be able to retrieve the decoded data unless the Squid maintainer had configured the display of usernames on error pages.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

The flaws in the HTTP Digest Authentication processing, the HTTP Basic Authentication processing and in the cachemgr.cgi allowed remote attackers to perform denial of service and cross-site scripting attacks, and potentially the execution of arbitrary code.

    descriptionSquid, a high-performance proxy caching server for web clients, has been found vulnerable to denial of service attacks associated with HTTP authentication header processing. CVE-2019-12525 Due to incorrect buffer management Squid is vulnerable to a denial of service attack when processing HTTP Digest Authentication credentials. Due to incorrect input validation the HTTP Request header parser for Digest authentication may access memory outside the allocated memory buffer. On systems with memory access protections this can result in the Squid process being terminated unexpectedly. Resulting in a denial of service for all clients using the proxy. CVE-2019-12529 Due to incorrect buffer management Squid is vulnerable to a denial of service attack when processing HTTP Basic Authentication credentials. Due to incorrect string termination the Basic authentication credentials decoder may access memory outside the decode buffer. On systems with memory access protections this can result in the Squid process being terminated unexpectedly. Resulting in a denial of service for all clients using the proxy. For Debian 8
