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.

IBM QRadar 7.2 is vulnerable to cross-site scripting. This vulnerability allows users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session. IBM Reference #: 1999534.

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.

IBM QRadar 7.2 stores the encryption key used to encrypt the service account password which can be obtained by a local user. IBM Reference #: 1997340.

IBM QRadar 7.2 uses outdated hashing algorithms to hash certain passwords, which could allow a local user to obtain and decrypt user credentials. IBM Reference #: 1997341.

IBM QRadar 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: 119737.

IBM QRadar 7.2 and 7.3 discloses sensitive information to unauthorized users. The information can be used to mount further attacks on the system. IBM X-Force ID: 122957.

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 attacker to obtain sensitive information, caused by the failure to properly enable HTTP Strict Transport Security. An attacker could exploit this vulnerability to obtain sensitive information using man in the middle techniques. IBM X-Force ID: 120208.

IBM QRadar 7.2 and 7.3 does not require that users should have strong passwords by default, which makes it easier for attackers to compromise user accounts. IBM X-Force ID: 119783.

IBM QRadar 7.2 discloses sensitive information to unauthorized users. The information can be used to mount further attacks on the system. IBM Reference #: 1999533.

IBM QRadar 7.2 does not perform an authentication check for a critical resource or functionality allowing anonymous users access to protected areas. IBM Reference #: 1999545.

IBM QRadar 7.2 could allow a remote attacker to consume all resources on the server due to not properly restricting the size or amount of resources requested by an actor. IBM Reference #: 1999556.
