FortiDAST performs automated black-box dynamic application security testing of web applications to identify vulnerabilities that bad actors may exploit.
This article describes the assessment of Improper Access Control Vulnerability in PaperCut MF and NG product with FortiDAST.
CVE-2023-27350 is an unauthenticated remote code execution vulnerability in PaperCut MF/NG print management software that allows attackers to bypass authentication and execute arbitrary code as SYSTEM on vulnerable targets.
Scope
FortiDAST Scripting Engine updated in version 23.3.a
Solution
Detection against that vulnerability is empowered by the FortiDAST Scripting Engine (FSE).
This technology enables FortiDAST to assess remotely with a high level of confidence if an asset is vulnerable to a specific vulnerability by testing the disarmed exploit against the asset itself.
To configure the scan, it will be necessary to enable the FSE group signature ‘papercut’ which will select the underlying script: ‘CVE-2023-27350 PaperCut Improper Access Control vulnerability.’
For reference, a step-by-step guide on how to configure FortiDAST to trigger FSE can be found on Fortinet’s blog:
