Stormshield Network Security
Monthly
Stored cross-site scripting in Stormshield Network Security's web administration panel allows an authenticated administrator who injects malicious script into group comments within the webservices interface to execute arbitrary JavaScript in the browser session of any other administrator who subsequently views that group entry. The CVSS 4.3 score reflects the constrained preconditions: adjacent network access, high privileges, and required user interaction by a second victim. No public exploit code and no CISA KEV listing have been identified at time of analysis.
Secret credential leakage in StormShield Network Security's CLI tool exposes the proxy CA passphrase or TPM password to other users sharing an SSH session on the firewall appliance. Affected versions span three distinct branches - 4.3.0-4.3.41, 4.8.0-4.8.15, and 5.0.0-5.0.5 - and exploitation is gated behind SSH multiuser mode being explicitly enabled. No active exploitation has been confirmed by CISA KEV and no public proof-of-concept has been identified at time of analysis, though the leaked secrets carry high downstream value for privilege escalation or certificate authority abuse.
Administrative access to the Stormshield Network Security captive-admin portal is bypassed when an attacker presents a revoked client certificate, because the portal does not enforce certificate revocation checks during TLS mutual authentication. Affected versions span three branches: 4.3.0-4.3.41, 4.4.0-4.8.15, and 5.0.2 EA-5.0.5. No public exploit has been identified at time of analysis and the vulnerability is absent from CISA KEV, but the threat actor population is meaningfully constrained - exploitation requires prior possession of a certificate that was specifically issued for this portal and then revoked.
