IBM QRadar SIEM 7.3, 7.4, and 7.5 may be vulnerable to partial denial of service attack, resulting in some protocols not listening to specified ports. IBM X-Force ID: 214028.

IBM QRadar SIEM 7.3 and 7.4 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM X-Force ID: 201778.

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 7.4.2 GA to 7.4.2 Patch 1, 7.4.0 to 7.4.1 Patch 1, and 7.3.0 to 7.3.3 Patch 5 could allow a remote attacker to traverse directories on the system. An attacker could send a specially-crafted URL request containing "dot dot" sequences (/../) to view arbitrary files on the system. IBM X-Force ID: 189302.

IBM QRadar SIEM 7.4.2 GA to 7.4.2 Patch 1, 7.4.0 to 7.4.1 Patch 1, and 7.3.0 to 7.3.3 Patch 5 is vulnerable to server side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks. IBM X-Force ID: 189224.

IBM QRadar SIEM 7.4.2 GA to 7.4.2 Patch 1, 7.4.0 to 7.4.1 Patch 1, and 7.3.0 to 7.3.3 Patch 5 is vulnerable to server side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks. IBM X-Force ID: 189221.

IBM QRadar SIEM 7.3 and 7.4 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 X-Force ID: 182364.

IBM QRadar SIEM 7.2 and 7.3 specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. IBM X-Force ID: 155350.

IBM QRadar 7.2 and 7.3 could allow a remote authenticated attacker to execute arbitrary commands on the system. By sending a specially-crafted request, an attacker could exploit this vulnerability to execute arbitrary commands on the system. IBM X-Force ID: 143121.

IBM QRadar Incident Forensics (IBM QRadar SIEM 7.2, and 7.3) could allow a remote attacker to bypass authentication and obtain sensitive information. IBM X-Force ID: 144164.
