Red Hat JBoss Authentication Bypass
CVE-2010-0738 is a medium-severity exposed dangerous method or function vulnerability in Jboss Enterprise Application Platform from Red Hat, with a CVSS 3.1 base score of 5.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Jboss Enterprise Application Platform versions: 4.2.0; 4.3.0. The record does not name a fixed version, so check the vendor advisory. CISA added it to the Known Exploited Vulnerabilities catalogue on May 25, 2022, which means attacks have been observed in the wild, including in ransomware campaigns.
Attackers are already exploiting this vulnerability, according to CISA.
What to do
- Check which version of Jboss Enterprise Application Platform you run against the affected versions below, and install the vendor's latest release.
- CISA's required action: Apply updates per vendor instructions.
- Read the advisory on rhn.redhat.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
The JMX-Console web application in JBossAs in Red Hat JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.2 before 4.2.0.CP09 and 4.3 before 4.3.0.CP08 performs access control only for the GET and POST methods, which allows remote attackers to send requests to this application's GET handler by using a different method.

The underlying weakness: Exposed Dangerous Method or Function
The product provides an Applications Programming Interface (API) or similar interface for interaction with external actors, but the interface includes a dangerous method or function that is not properly restricted.
How developers prevent this class of flaw
- If you must expose a method, make sure to perform input validation on all arguments, limit access to authorized parties, and protect against all possible vulnerabilities.
- Identify all exposed functionality. Explicitly list all functionality that must be exposed to some user or set of users. Identify which functionality may be: accessible to all users restricted to a small set of privileged users prevented from being directly accessible at all Ensure that the implemented code follows these expectations. This includes setting the appropriate access modifiers where applicable (public, private, protected, etc.) or not marking ActiveX controls safe-for-scripting.
