Description

MoinMoin 1.9 before 1.9.1 does not perform the expected clearing of the sys.argv array in situations where the GATEWAY_INTERFACE environment variable is set, which allows remote attackers to obtain sensitive information via unspecified vectors.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every moinmo moinmoin 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-2010-0667 yet — track the moinmo moinmoin 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-2010-0667 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-2010-0667. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
