A10 ACOS Web Application Firewall (WAF) 2.7.1 and 2.7.2 before 2.7.2-P12, 4.1.0 before 4.1.0-P11, 4.1.1 before 4.1.1-P8, and 4.1.2 before 4.1.2-P4 mishandles the configured rules for blocking SQL injection attacks, aka A10-2017-0008.

Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4.

The Application Firewall Pack (AFP, aka Web Application Firewall) component on Kemp Load Balancer devices with software before 7.2.40.1 allows a Security Feature Bypass via an HTTP POST request.

DenyAll WAF before 6.4.1 allows unauthenticated remote attackers to obtain authentication information by making a typeOf=debug request to /webservices/download/index.php, and then reading the iToken field in the reply. This affects DenyAll i-Suite LTS 5.5.0 through 5.5.12, i-Suite 5.6, Web Application Firewall 5.7, and Web Application Firewall 6.x before 6.4.1, with On Premises or AWS/Azure cloud deployments.

DenyAll WAF before 6.4.1 allows unauthenticated remote command execution via TCP port 3001 because shell metacharacters can be inserted into the type parameter to the tailDateFile function in /webservices/stream/tail.php. An iToken authentication parameter is required but can be obtained by exploiting CVE-2017-14706. This affects DenyAll i-Suite LTS 5.5.0 through 5.5.12, i-Suite 5.6, Web Application Firewall 5.7, and Web Application Firewall 6.x before 6.4.1, with On Premises or AWS/Azure cloud deployments.

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.

Cross-site scripting (XSS) vulnerability in the Violations Table in the management GUI in the MX Management Server in Imperva SecureSphere Web Application Firewall (WAF) 9.0 allows remote attackers to inject arbitrary web script or HTML via the username field.

IBM Web Application Firewall, as used on the G400 IPS-G400-IB-1 and GX4004 IPS-GX4004-IB-2 appliances with update 31.030, does not properly handle query strings with multiple instances of the same parameter, which allows remote attackers to bypass intended intrusion prevention by dividing a dangerous parameter value into substrings, as demonstrated by a SQL statement that is split across multiple iid parameters and then sent to a .aspx file on an IIS web server.

Cross-site scripting (XSS) vulnerability in the management GUI in the MX Management Server in Imperva SecureSphere Web Application Firewall 6.2, 7.x, and 8.x allows remote attackers to inject arbitrary web script or HTML via an HTTP request to a firewalled server, aka Bug ID 31759.

Imperva SecureSphere Web Application Firewall and Database Firewall 5.0.0.5082 through 7.0.0.7078 allow remote attackers to bypass intrusion-prevention functionality via a request that has an appended long string containing an unspecified manipulation.
