CVE-2024-53704: An Improper Authentication vulnerability in the SSLVPN authentication mechanism allows a remote attacker to bypass authentication.
Noroxi assessment
Priority: Now (action score 98/100)
- CISA has confirmed exploitation in the wild (Feb 18, 2025); it is known to be used in ransomware campaigns. Remediation deadline for US federal agencies: Mar 11, 2025.
- A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
- Probability of exploitation in the next 30 days: 95.3% (FIRST EPSS); higher than 99.8% of all records.
- Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to CISA the attack is automatable: targets can be found by mass scanning.
- According to the record, no fixed version is available yet.
Patch today or shut off access. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Root cause
Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.
