How do I patch CVE-2013-7398?

No patch has shipped for CVE-2013-7398 yet — track the async-http-client_project async-http-client advisory for a fixed release and apply the workarounds below in the meantime.

How do I detect CVE-2013-7398 across my infrastructure?

Inventory every async-http-client_project async-http-client 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.

How do I mitigate CVE-2013-7398 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-2013-7398?

O3 detects and blocks CVE-2013-7398 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-2013-7398 actively exploited in the wild?

No public exploit code has been indexed for CVE-2013-7398 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-2013-7398?

CVE-2013-7398 has an EPSS (Exploit Prediction Scoring System) score of 0.8%, placing it in the 53th 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-2013-7398?

CVE-2013-7398 is classified as CWE-345 (CWE-345). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

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

main/java/com/ning/http/client/AsyncHttpClientConfig.java in Async Http Client (aka AHC or async-http-client) before 1.9.0 does not require a hostname match during verification of X.509 certificates, which allows man-in-the-middle attackers to spoof HTTPS servers via an arbitrary valid certificate.
