CVE-2024-55557
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 · uneditedui/pref/ProxyPrefView.java in weasis-core in Weasis 4.5.1 has a hardcoded key for symmetric encryption of proxy credentials.
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 · high confidenceWeasis 4.5.1 contains a hardcoded symmetric encryption key in ProxyPrefView.java used to encrypt proxy credentials. An attacker with access to the source code or binary can recover this key and decrypt stored proxy credentials, potentially gaining unauthorized network access.

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.
-
Identify Weasis installation and versionLocate the Weasis installation directory and check the version. On Windows, look in Program Files\Weasis or similar. Check for a version file or the main JAR filename which typically includes the version number.Affected if The installed version is 4.5.1 exactly.
-
Check for proxy configurationExamine Weasis configuration files for proxy settings. Look in the Weasis config directory for files like preferences.properties, weasis.properties, or any XML configuration files that may contain proxy_host, proxy_port, proxy_username, or proxy_password entries.Affected if Proxy credentials (username and password) are configured and stored in Weasis configuration files.
-
Inspect stored credential filesSearch the Weasis configuration and data directories for files that may contain encrypted proxy credentials. Common locations include the user home directory under .weasis or the Weasis config folder. Look for files with names containing 'proxy', 'pref', or 'credentials'.Affected if Encrypted proxy credentials exist in stored configuration files that were encrypted using the hardcoded key.
-
Verify the vulnerable class existsIf accessible, examine the Weasis JAR file (weasis-core-*.jar) and locate ProxyPrefView.java or its compiled class file ProxyPrefView.class. The presence of this class indicates the vulnerable code path is included.Affected if The ProxyPrefView class is present in the Weasis installation, indicating the hardcoded key may be used for credential encryption.
You are affected if you have Weasis version 4.5.1 installed AND have configured proxy credentials that are stored locally, as these credentials were encrypted using the hardcoded symmetric key.

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 dataReplace the hardcoded encryption key with a proper key management solution (e.g., OS keychain, external KMS, or derived key based on user credentials). Migrate existing stored credentials to the new encryption scheme.
