Which products are affected by CVE-2013-2185?

Affected package information for CVE-2013-2185 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2013-2185?

No patch has shipped for CVE-2013-2185 yet — track the apache tomcat advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2013-2185 across my infrastructure?

Inventory every apache tomcat 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 remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2013-2185 if there is no patch (or I can't update yet)?

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.

How does O3 Security protect against CVE-2013-2185?

O3 detects and blocks CVE-2013-2185 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2013-2185 actively exploited in the wild?

No public exploit code has been indexed for CVE-2013-2185 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2013-2185?

CVE-2013-2185 has an EPSS (Exploit Prediction Scoring System) score of 7.2%, placing it in the 94th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2013-2185?

CVE-2013-2185 is classified as Improper Input Validation (CWE-20). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

Which products and versions are affected by CVE-2013-2185?

CVE-2013-2185 affects apache tomcat; redhat jboss enterprise application platform (1 version, e.g. 6.1.0); redhat jboss enterprise portal platform (1 version, e.g. 6.0.0). Check the affected-products list on this page against your deployed version to confirm exposure.

When was CVE-2013-2185 published, and has it been updated?

CVE-2013-2185 was published on January 19, 2014 and was last updated on June 16, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.

Description

The readObject method in the DiskFileItem class in Apache Tomcat and JBoss Web, as used in Red Hat JBoss Enterprise Application Platform 6.1.0 and Red Hat JBoss Portal 6.0.0, allows remote attackers to write to arbitrary files via a NULL byte in a file name in a serialized instance, a similar issue to CVE-2013-2186. NOTE: this issue is reportedly disputed by the Apache Tomcat team, although Red Hat considers it a vulnerability. The dispute appears to regard whether it is the responsibility of applications to avoid providing untrusted data to be deserialized, or whether this class should inherently protect against this issue
