Apache Tomcat CVE-2019-0232 Remote Code Execution Vulnerability

Description

Apache Tomcat is prone to a remote code-execution vulnerability. Successfully exploiting this issue allows attackers to execute arbitrary code in the context of the affected application. Apache Tomcat version 9.0.0.M1 through 9.0.17, 8.5.0 through 8.5.39 and 7.0.0 through 7.0.93 are vulnerable.

Recommendations

Do not accept or execute files from untrusted or unknown sources.
To reduce the likelihood of successful exploits, never handle files that originate from unfamiliar or untrusted sources.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.

Run all software as a nonprivileged user with minimal access rights.
To limit the impact of latent vulnerabilities, configure database servers and other applications to run as a nonadministrative user with minimal access rights.

Updates are available. Please see the references or vendor advisory for more information.
