A security bypass vulnerability in Network-AI SandboxPolicy allows authenticated attackers to circumvent blocklists due to improper quote handling.

This vulnerability is an interpretation conflict (CWE-436) where the software fails to correctly parse quotes within the SandboxPolicy blocklist. An attacker with low privileges can exploit this mismatch to bypass security restrictions that would otherwise block their actions.

The CVSS score of 8.8 indicates a high-severity risk. By bypassing the sandbox blocklist, an attacker can execute restricted operations, leading to unauthorized access, potential data exfiltration, or the circumvention of established organizational security policies.

Immediate Action: Upgrade Network-AI to version 5.15.1 or later, which contains the necessary patches for blocklist interpretation errors.

Proactive Monitoring: Audit logs for suspicious activity that suggests attempts to probe or bypass sandbox restrictions, specifically looking for unusual character usage in policy-related inputs.

Compensating Controls: If upgrading is delayed, use a WAF to inspect and filter traffic for patterns that utilize quote-based obfuscation to evade blocklist filters.

Public Exploit Available: No (unknown)

Users should prioritize upgrading to version 5.15.1 to resolve this vulnerability. Relying on current security policies without this update leaves the system exposed to bypass attacks that could undermine the entire sandbox architecture.
