Base vector

AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: PrusaSlicer versions 2.2.0 and Master (commit 4b040b856)

Description: An out-of-bounds write issue exists in the load obj() functionality of the Obj.cpp file. This can be triggered by a specially crafted obj file, potentially leading to code execution. An attacker can exploit this by providing a malicious file.

Recommendations: For version 2.2.0, consider disabling the load obj() function in the Obj.cpp file until a patch is available. For Master (commit 4b040b856), restrict the use of the Obj.cpp file to minimize the risk of exploitation. As a temporary workaround, avoid using the Obj.cpp file with untrusted obj files until the issue is resolved.
