CVE-2023-50314
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM WebSphere Application Server Liberty 17.0.0.3 through 24.0.0.8 could allow an attacker with access to the network to conduct spoofing attacks. An attacker could exploit this vulnerability using a certificate issued by a trusted authority to obtain sensitive information. IBM X-Force ID: 274713.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIBM WebSphere Application Server Liberty versions 17.0.0.3 through 24.0.0.8 contains a certificate validation flaw that allows an attacker with network access to perform spoofing attacks using a legitimately-issued certificate from a trusted certificate authority, potentially leading to unauthorized access and sensitive information disclosure.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Determine installed WebSphere Liberty versionCheck the version file in the Liberty installation directory. Run 'java -jar wlp/lib/versions/*.jar' or inspect the 'product.info' file typically located in 'lib/versions/' or 'bin/productInfo' to obtain the exact version number.Affected if The installed version falls within the range 17.0.0.3 through 24.0.0.8 inclusive.
-
Confirm SSL/TLS is enabledInspect the server.xml configuration file (typically in the 'usr/servers/<serverName>/' directory) for SSL or TLS configuration elements such as <ssl> or <keyStore> that indicate SSL/TLS is in use.Affected if SSL or TLS is configured and enabled on the server.
-
Verify client certificate authentication settingsReview the SSL configuration in server.xml for attributes such as 'clientAuthentication' or 'clientAuth' to determine if client certificate authentication is required or optional.Affected if Client certificate authentication is enabled or configured, as this vulnerability affects certificate validation in both client and server contexts.
-
Check for custom certificate trust settingsExamine the SSL configuration for 'trustManager' or 'trustStore' settings in server.xml that define custom trust behavior, as these may indicate custom certificate validation is in use.Affected if Custom trust managers or non-default trust stores are configured, which could bypass default certificate validation.
You are affected if your WebSphere Application Server Liberty version is between 17.0.0.3 and 24.0.0.8 and you have SSL/TLS enabled with certificate validation in use.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply IBM's security patch or upgrade WebSphere Application Server Liberty to a version newer than 24.0.0.8 to address the certificate validation vulnerability.
