bash: specially-crafted environment variables can be used to inject shell commands

GNU Bash through 4.3 processes trailing strings after function definitions in the values of environment variables, which allows remote attackers to execute arbitrary code via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid 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, aka "ShellShock." NOTE: the original fix for this issue was incorrect; CVE-2014-7169 has been assigned to cover the vulnerability that is still present after the incorrect fix.

bash: code execution via specially-crafted environment (Incomplete fix for CVE-2014-6271)

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 mod_cgi and mod_cgid 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 Access Manager for Web could allow an authenticated user to gain access to highly sensitive information due to incorrect file permissions.

IBM Security Access Manager for Web could allow an unauthenticated user to gain access to sensitive information by entering invalid file names.

IBM Security Access Manager for Web allows web pages to be stored locally which can be read by another user on the system.

IBM Security Access Manager for Web is vulnerable to a denial of service, caused by an XML External Entity Injection (XXE) error when processing XML data. A remote attacker could exploit this vulnerability to expose highly sensitive information or consume all available memory resources.

IBM Security Access Manager for Web is vulnerable to cross-site request forgery which could allow an attacker to execute malicious and unauthorized actions transmitted from a user that the website trusts.

IBM Security Access Manager for Web 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 Security Access Manager for Web is vulnerable to SQL injection. A remote attacker could send specially-crafted SQL statements which could allow the attacker to view information in the back-end database.

IBM Security Access Manager for Web 7.0.0, 8.0.0, and 9.0.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information. IBM Reference #: 1996868.

The IBM Security Access Manager appliance includes configuration files that contain obfuscated plaintext-passwords which authenticated users can access.

IBM Single Sign On for Bluemix could allow a remote attacker to obtain sensitive information, caused by a XML external entity (XXE) error when processing XML data by the XML parser. A remote attacker could exploit this vulnerability to read arbitrary files on the system or cause a denial of service.

IBM Security Access Manager for Web processes patches, image backups and other updates without sufficiently verifying the origin and integrity of the code, which could allow an authenticated attacker to load malicious code.

IBM Security Access Manager for Web 7.0.0, 8.0.0, and 9.0.0 could allow a remote attacker to bypass security restrictions, caused by improper content validation. By persuading a victim to open specially-crafted content, an attacker could exploit this vulnerability to bypass validation and load a page with malicious content.

IBM Security Access Manager for Web could allow a remote attacker to obtain sensitive information due to security misconfigurations.

IBM Security Access Manager for Web could allow an authenticated attacker to obtain sensitive information from error message using a specially crafted HTTP request.

The reverse-proxy feature in IBM Security Access Manager (ISAM) for Web 8.0 with firmware 8.0.0.2 and 8.0.0.3 interprets the jct-nist-compliance parameter in the opposite of the intended manner, which makes it easier for remote attackers to obtain sensitive information by leveraging weak SSL encryption settings that lack NIST SP 800-131A compliance.

The Local Management Interface (LMI) in IBM Security Access Manager (ISAM) for Mobile 8.0 with firmware 8.0.0.0 through 8.0.0.3 and IBM Security Access Manager for Web 7.0, and 8.0 with firmware 8.0.0.2 and 8.0.0.3, allows remote attackers to bypass authentication via a login action with invalid credentials.

The WebSEAL component in IBM Security Access Manager for Web 7.x before 7.0.0-ISS-WGA-IF0009 and 8.x before 8.0.0-ISS-WGA-FP0005, when e-community SSO is enabled, allows remote attackers to cause a denial of service (component hang) via unspecified vectors.

The administration console in IBM Security Access Manager for Web 7.x before 7.0.0-ISS-WGA-IF0009 and 8.x before 8.0.0-ISS-WGA-FP0005, and Security Access Manager for Mobile 8.x before 8.0.0-ISS-ISAM-FP0005, allows remote attackers to inject system commands via unspecified vectors.
