CVE-2023-2621
The McFeeder server (distributed as part of SSW package), is susceptible to an arbitrary file write vulnerability on the MAIN computer system.
Does this matter?
Lower severity and a low EPSS score (0.49%). Track it; it rarely justifies an emergency change on its own.
Description
The McFeeder server (distributed as part of SSW package), is susceptible to an arbitrary file write vulnerability on the MAIN computer system. This vulnerability stems from the use of an outdated version of a third-party library, which is used to extract archives uploaded to McFeeder server. An authenticated malicious client can exploit this vulnerability by uploading a crafted ZIP archive via the network to McFeeder’s service endpoint.
