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 attacker to obtain sensitive information from error message using a specially crafted HTTP request.

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 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 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.

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 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 7.0.0 before FP19 and 8.0 before 8.0.1.3 IF3, and Security Access Manager 9.0 before 9.0.0.0 IF1, allows remote authenticated users to execute arbitrary OS commands by leveraging Local Management Interface (LMI) access.

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.

Cross-site scripting (XSS) vulnerability in the Local Management Interface 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 arbitrary web script or HTML via a crafted URL.

The Multicast DNS (mDNS) responder in IBM Security Access Manager for Web 7.x before 7.0.0 FP12 and 8.x before 8.0.1 FP1 inadvertently responds to unicast queries with source addresses that are not link-local, which allows remote attackers to cause a denial of service (traffic amplification) or obtain potentially sensitive information via port-5353 UDP packets.

IBM Security Access Manager for Web 7.0 before 7.0.0 IF21, 8.0 before 8.0.1.3 IF4, and 9.0 before 9.0.0.1 IF1 does not have a lockout mechanism for invalid login attempts, which makes it easier for remote attackers to obtain access via a brute-force attack.

The SSH implementation on IBM Security Access Manager for Web appliances 7.0 before 7.0.0 FP19, 8.0 before 8.0.1.3 IF3, and 9.0 before 9.0.0.0 IF1 does not properly restrict the set of MAC algorithms, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via unspecified vectors.

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.
