Critical Vulnerabilities in PaperCut Print Management Software
Our team is tracking in-the-wild exploitation of zero-day vulnerabilities against PaperCut MF/NG which allow for unauthenticated remote code execution due to an authentication bypass.
in February 2023, Kaspersky technologies detected a number of attempts to execute similar elevation-of-privilege exploits on Microsoft Windows servers belonging to small and medium-sized businesses in the Middle East, in North America, and previously in Asia regions. These exploits were very similar to already known Common Log File System (CLFS) driver exploits that we analyzed previously, but we decided to double check and it was worth it – one of the exploits turned out to be a zero-day, supporting different versions and builds of Windows, including Windows 11. The exploit was highly obfuscated with more than 80% of the its code being “junk” elegantly compiled into the binary, but we quickly fully reverse-engineered it and reported our findings to Microsoft. Microsoft assigned CVE-2023-28252 to the Common Log File System elevation-of-privilege vulnerability, and a patch was released on April 11, 2023, as part of April Patch Tuesday.
