Apache Tomcat RemoteFilterValve security bypass
| apache-tomcat-valve-security-bypass (45791) |  Medium Risk |
Description:
Apache Tomcat could allow a remote attacker to bypass security restrictions, caused by an error in valves that extend the RemoteFilterValve, including the RemoteAddrValve and RemoteHostValve implementations. A remote attacker could exploit this vulnerability using a request that is processed concurrently with another request but in a different thread to allow a user from a non-permitted IP address to gain access to protected context.
