IBM QRadar is vulnerable to an XML External Entity Injection (XXE) attack when processing XML data. A remote attacker could exploit this vulnerability to expose sensitive information or consume memory resources.

IBM QRadar SIEM 7.4.0 to 7.4.2 Patch 1 and 7.3.0 to 7.3.3 Patch 7 could allow a remote attacker to execute arbitrary commands on the system, caused by insecure deserialization of user-supplied content by the Java deserialization function. By sending a malicious serialized Java object, an attacker could exploit this vulnerability to execute arbitrary commands on the system. IBM X-Force ID: 190912.

IBM QRadar SIEM 7.3 and 7.4 is vulnerable to insecure inter-deployment communication. An attacker that is able to comprimise or spoof traffic between hosts may be able to execute arbitrary commands. IBM X-Force D: 192538.

IBM QRadar SIEM 7.3, 7.4, and 7.5 in some situations may not automatically log users out after they exceede their idle timeout. IBM X-Force ID: 208341.

IBM QRadar SIEM 7.3 and 7.4 could allow a remote privileged user to execute commands.
