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 InfoSphere Guardium 8.0, 8.01, and 8.2 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 download arbitrary files on the system. IBM X-Force ID: 78284.

IBM InfoSphere Guardium 8.0, 8.01, and 8.2 is vulnerable to SQL injection. A remote authenticated attacker could send specially-crafted SQL statements to multiple scripts, which could allow the attacker to view, add, modify or delete information in the back-end database. IBM X-Force ID: 78282.

IBM InfoSphere Guardium 8.0, 8.01, and 8.2 could allow a remote attacker to bypass security restrictions, caused by improper restrictions on the create new user account functionality. An attacker could exploit this vulnerability to create unprivileged user accounts. IBM X-Force ID: 78286.

Cross-site request forgery (CSRF) vulnerability in the account-creation panel in IBM InfoSphere Guardium 8.2 and earlier, when the CSRF filtering (aka csrfstatus) feature is disabled, allows remote attackers to hijack the authentication of administrators for requests that create administrative accounts.

The datasource definition editor in IBM InfoSphere Guardium 8.2 and earlier, when the save-password setting is enabled, transmits cleartext database credentials, which allows remote attackers to obtain sensitive information by sniffing the network.

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 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.
