CVE-2012-5575
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 · uneditedApache CXF 2.5.x before 2.5.10, 2.6.x before CXF 2.6.7, and 2.7.x before CXF 2.7.4 does not verify that a specified cryptographic algorithm is allowed by the WS-SecurityPolicy AlgorithmSuite definition before decrypting, which allows remote attackers to force CXF to use weaker cryptographic algorithms than intended and makes it easier to decrypt communications, aka "XML Encryption backwards compatibility attack."
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 confidenceApache CXF versions 2.5.x before 2.5.10, 2.6.x before 2.6.7, and 2.7.x before 2.7.4 fail to validate that cryptographic algorithms used in XML decryption comply with the WS-SecurityPolicy AlgorithmSuite definition. This allows an attacker to force the use of weaker algorithms by specifying them in encrypted content, enabling a 'XML Encryption backwards compatibility attack' that weakens confidentiality.

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 Apache CXF versionLocate the CXF JAR files (cxf-*.jar) in your application's classpath or lib directory and examine the version number in the filename. Alternatively, check the MANIFEST.MF file inside the CXF JAR for the Implementation-Version attribute.Affected if The version is 2.5.x before 2.5.10, 2.6.x before 2.6.7, or 2.7.x before 2.7.4, or if the version cannot be determined but falls within these ranges.
-
Confirm WS-SecurityPolicy is in useReview your application configuration files (such as XML configuration files, WSDL files with WS-Policy assertions, or Spring/Blueprint configuration files) for the presence of WS-SecurityPolicy elements, specifically the AlgorithmSuite policy definition.Affected if WS-SecurityPolicy is configured for XML encryption or digital signatures without an explicit AlgorithmSuite definition, or the AlgorithmSuite allows algorithm negotiation.
-
Inspect AlgorithmSuite configurationExamine your WS-SecurityPolicy configuration for the AlgorithmSuite element. Look for whether a specific algorithm suite (such as Basic256, TripleDes, or custom) is explicitly defined, or if the configuration relies on defaults or allows client-specified algorithms.Affected if The AlgorithmSuite is not explicitly defined or allows unspecified algorithms that could be downgraded by an attacker.
-
Check for Red Hat JBoss productsIf using Red Hat JBoss Enterprise Application Platform, Portal Platform, SOA Platform, Web Platform, or Fuse ESB Enterprise, identify the CXF version bundled with the product by checking the included libraries or release notes.Affected if The bundled CXF version falls within the affected version ranges listed (EAP 5.0.0, Portal 4.3.0, SOA 4.3.0, Web 5.2.0, Fuse 7.1.0).
You are affected if your environment runs Apache CXF versions 2.5.x before 2.5.10, 2.6.x before 2.6.7, or 2.7.x before 2.7.4 (or corresponding Red Hat product versions) AND uses WS-SecurityPolicy for XML encryption without explicitly defined AlgorithmSuite constraints.

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 dataUpgrade Apache CXF to version 2.5.10, 2.6.7, or 2.7.4 or later. If upgrade is not immediately possible, audit WS-SecurityPolicy configurations to ensure AlgorithmSuite constraints are explicitly defined and consider network-level controls to block downgrade attempts.
