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.

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 Security Guardium Database Activity Monitor 9.0, 9.1, and 9.5 could allow a local user with low privileges to view report pages and perform some actions that only an admin should be performing, so there is risk that someone not authorized can change things that they are not suppose to. IBM X-Force ID: 137765.

IBM Security Guardium Database Activity Monitor 8.2 before p310, 9.x through 9.5 before p700, and 10.x through 10.1 before p100 allows local users to obtain administrator privileges for command execution via unspecified vectors.

IBM Security Guardium Database Activity Monitor 9.x through 9.5 before p700 and 10.x through 10.0.1 before p100 allows remote authenticated users to make HTTP requests with administrator privileges via unspecified vectors.

IBM Security Guardium Database Activity Monitor 8.2 before p310, 9.x through 9.5 before p700, and 10.x through 10.1 before p100 allows remote authenticated users to spoof administrator accounts by sending a modified login request over HTTP.

IBM Security Guardium Database Activity Monitor 8.2 before p310, 9.x through 9.5 before p700, and 10.x through 10.1 before p100 allows remote authenticated users to execute arbitrary commands with root privileges via the search field.

IBM Security Guardium Database Activity Monitor 8.2 before p310, 9.x through 9.5 before p700, and 10.x through 10.1 before p100 does not enable the HSTS protection mechanism, which makes it easier for remote attackers to obtain sensitive information by leveraging use of HTTP.
