Description

SabreDAV before 1.7.11, as used in ownCloud Server before 5.0.15 and 6.0.x before 6.0.2, allows remote attackers to read arbitrary files, cause a denial of service, or possibly have other impact via an XML External Entity (XXE) attack.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for sabre/dav, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update sabre/dav to 1.7.11 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2014-2055 is resolved across your whole dependency graph.

  3. Workarounds

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

  4. How O3 protects you

    O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like CVE-2014-2055 can be triaged on real exposure rather than presence alone.

Tailored to CVE-2014-2055. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
