Horizon Alert
Summary of the vulnerability and why it matters
This vulnerability impacts PaperCut NG and PaperCut MF software. The core issue lies in an improper implementation of the authentication algorithm within the SecurityRequestFilter class. This flaw permits unauthenticated remote attackers to bypass system authentication.
- Affected software components
- Authentication bypass flaw
- Compromised system access
Attack Path
How an attacker could exploit the issue
The vulnerability affects PaperCut NG and PaperCut MF software. Attackers can exploit this by sending specially crafted requests to bypass authentication on the affected system. This bypass allows unauthorized access to the system, potentially leading to further compromise. The vulnerability exists within the SecurityRequestFilter class due to an improper implementation of the authentication algorithm.
- Network exposure required
- Attacker sends crafted request
- Bypasses authentication, gains access
Live Threat
