DescriptionCVE.org
Bridge versions 15.1.3, 16.0.1 and earlier are affected by an Integer Overflow or Wraparound vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
Executive ViewAI
A high-severity integer overflow vulnerability in Bridge versions 15.1.3 and earlier enables arbitrary code execution when users open malicious files. This represents a significant risk to any organization using affected Bridge versions, as successful exploitation grants attackers the same privileges as the victim user, potentially compromising sensitive data and systems.
Until patches are available: (1) Disable Bridge auto-file-opening features if possible; (2) Implement email filtering to restrict potentially malicious file attachments; (3) Use application whitelisting to prevent unauthorized code execution; (4) Segment affected systems on isolated network zones with restricted access; (5) Deploy endpoint detection and response (EDR) tools to monitor for exploitation attempts; (6) Enforce strict user access controls limiting use of affected systems to necessary personnel only.

Attack Technique
Integer overflow occurs when an arithmetic operation produces a result that exceeds the maximum value a given integer type can store.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
