IBM QRadar 7.6.0.0 through 7.6.0.1, and 7.5.0 through 7.5.0 UP 15 Interim Fix 005 has an XML External Entity (XXE) injection vulnerability. The vulnerability resides in the parseXmlPayload() function within the event processing pipeline ( q1labscore.jar ). When at least one log source type is configured to use XML-format property autodetection, the system processes XML-formatted syslog events sent to port 514 (UDP/TCP) without authentication.

IBM QRadar SIEM 7.5 through 7.5.0 Update Package 12 could allow a privileged user to modify configuration files that would allow the upload of a malicious autoupdate file to execute arbitrary commands.

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 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 7.3 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 7.4.0 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 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: 176140.

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

IBM QRadar SIEM 7.3.2 could allow a user to bypass authentication exposing certain functionality which could lead to information disclosure or modification of application configuration. IBM X-Force ID: 158986.

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 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: 134178.

IBM QRadar Incident Forensics 7.2 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 Reference #: 1999542.

IBM Security QRadar SIEM 7.1.x and 7.2.x before 7.2.7 allows remote authenticated users to execute arbitrary OS commands as root via unspecified vectors.

Unspecified vulnerability in IBM QRadar SIEM 7.1 MR2 before Patch 11 IF02 and 7.2.x before 7.2.5 Patch 4 allows remote authenticated users to execute arbitrary commands with root privileges via unknown vectors.

IBM QRadar SIEM 7.1 MR2 before Patch 11 IF02 and 7.2.x before 7.2.5 Patch 4 allows remote authenticated users to execute arbitrary commands with root privileges by leveraging admin access.

The xmlrpc.cgi Webmin script in IBM QRadar SIEM 7.1 MR2 before Patch 11 IF02 and 7.2.x before 7.2.5 Patch 4 allows remote authenticated users to execute arbitrary commands with root privileges via unspecified vectors.

Unspecified vulnerability in IBM Security QRadar SIEM 7.1 MR2 and 7.2 MR2 allows remote attackers to execute arbitrary code via unknown vectors.

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the modcgi and modcgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271.

A flaw was found in the bash functionality that evaluates specially formatted environment variables passed to it from another environment. An attacker could use this feature to override or bypass restrictions to the environment to execute shell commands before restrictions have been applied. Certain services and applications allow remote unauthenticated attackers to provide environment variables, allowing them to exploit this issue.
