On September 26, 2024, security researcher Simone Margaritellidisclosed the details of four OpenPrinting Common UNIX Printing System (CUPS) vulnerabilities, that, when chained together, can allow malicious actors to launch remote code execution (RCE) attacks on vulnerable systems. CUPS is a widely used, open-source printing system that supports Linux and other Unix-like operating systems. It also supports ChromeOS and macOS.

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.

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.
