The JexBoss Exploit Tool is a tool that allows attackers to generate exploits for vulnerabilities targeting JBoss Application Servers. The vectors that the JexBoss Exploit Tool uses to exploit systems are the /jmx-console
, and /invoker
While the JexBoss Exploit Tool may be used for testing purposes, its presence on users' systems or on the network may indicate malicious activity.
In a recent blog post by Cisco Talos, SamSam: The Doctor Will See You, After He Pays The Ransom
, attackers have been seen leveraging the JexBoss Exploit tool to exploit vulnerabilities in JBoss Application Servers to gain a foothold in the targeted network to spread a ransomware dubbed SamSam.
In addition, administrators are to be aware of the jbossass.war
file (MD5 checksum: CBDEAF83F58A64B09DF58B94063E0146), which is an indicator that the JexBoss Exploit Tool is being leveraged in their environments. Once a targeted system is infected, the attacker could execute arbitrary commands on the targeted JBoss Application Server.
Users are advised not to open email messages from suspicious or unrecognized sources. If users cannot verify that links or attachments included in email messages are safe, they are advised not to open them.
Administrators are advised to implement an intrusion prevention system (IPS) or intrusion detection system (IDS) to help detect and prevent attacks that attempt to exploit this vulnerability.
Administrators can apply Snort SID 38304 to help prevent attacks that attempt to leverage the JexBoss Exploit Tool.
