On September 26th, 2024, details were released about several vulnerabilities in the Common Unix Printing System (CUPS) package. A total of four CVE’s (CVE-2024-47176, CVE-2024-47076, CVE-2024-47175, and CVE-2024-47177) have been released, affecting many Unix and Linux distributions. Three of the vulnerabilities are rated High, while one is rated Critical. If left unpatched, a remote attacker is able to execute arbitrary commands on the affected system.

A series of critical vulnerabilities has been uncovered in the Common Unix Printing System (CUPS), specifically in the cups-browsed component and related libraries. This vulnerability chain allows remote, unauthenticated attackers to potentially execute arbitrary code with root privileges on affected systems. The discovery highlights significant security risks in a widely-used open-source component and raises crucial questions about legacy system support and security in modern IT environments.

CVE-2024-6670 is a critical (CVSS v3 score: 9.8) SQL injection vulnerability. Threat researcher Sina Kheirkhah (@SinSinology) of Summoning Team (@SummoningTeam) discovered that, if the application is configured with only one user, unauthenticated attackers can leverage this vulnerability to retrieve users’ encrypted passwords.

On September 26, 2024, a security researcher disclosed several vulnerabilities affecting Common UNIX Printing System (CUPS) within GNU/Linux distributions. CUPS is an open-source printing system that allows Unix-like operating systems, including Linux and MacOS, to manage printers and print jobs across local and networked environments. The newly identified CUPS vulnerabilities identified are.

On September 27, 2024, evilsocket.net (Simone Margaritelli) published information about several vulnerabilities in CUPS (Common UNIX Printing System), which can allow for arbitrary remote code execution (RCE). There are currently 4 CVEs associated with these findings, with potentially more on the way. There is also some debate about the severity of these vulnerabilities, however, one of the CVEs was initially given a CVSS score of 9.9. We will update this blog if new information becomes available.
