Apache Struts is prone to a remote code-execution vulnerability. Successfully exploiting this issue may allow an attacker to execute arbitrary code in the context of the affected application. Failed exploit attempts may cause a denial-of-service condition. Apache Struts 1.0 through 1.3.10 are vulnerable.
Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, run the application with the minimal amount of privileges required for functionality.
Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity including unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.
Do not follow links provided by unknown or untrusted sources.
To reduce the likelihood of attacks, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.
Implement multiple redundant layers of security.
Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attackerβs ability to exploit this vulnerability to execute arbitrary code.
