Description

** UNSUPPORTED WHEN ASSIGNED ** Incorrect Authorization vulnerability in Apache Archiva.

Apache Archiva has a setting to disable user registration, however this restriction can be bypassed. As Apache Archiva has been retired, we do not expect to release a version of Apache Archiva that fixes this issue. You are recommended to look into migrating to a different solution, or isolate your instance from any untrusted users.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every apache archiva deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

  2. Remediation status

    No patch has shipped for CVE-2024-27138 yet — track the apache archiva advisory for a fixed release and apply the workarounds below in the meantime.

  3. Mitigate without a patch

    Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

  4. How O3 protects you

    O3 detects and blocks CVE-2024-27138 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Tailored to CVE-2024-27138. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
