5.5.34- Upgrade org.apache.tomcat:tomcat to this version or later
Description
The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and 7.x before 7.0.12 does not have the expected countermeasures against replay attacks, which makes it easier for remote attackers to bypass intended access restrictions by sniffing the network for valid requests, related to lack of checking of nonce (aka server nonce) and nc (aka nonce-count or client nonce count) values.
Affected versions
Maven
| Package | Vulnerable | Fixed in |
|---|---|---|
| org.apache.tomcat:tomcat | >= 5.5.0, < 5.5.34 |
5.5.34 |
| org.apache.tomcat:tomcat | >= 6.0.0, < 6.0.33 |
6.0.33 |
| org.apache.tomcat:tomcat | >= 7.0.0, < 7.0.12 |
7.0.12 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
