SB2023091805 - Multiple vulnerabilities in IBM CICS TX Advanced

Description

This security bulletin contains information about 4 secuirty vulnerabilities.

1) Code Injection (CVE-ID: CVE-2023-24540)

The vulnerability allows a remote attacker to execute arbitrary JavaScript code.

The vulnerability exists due to improper input validation when processing whitespace characters. A remote attacker can send a specially crafted request and execute arbitrary JavaScript code.

2) Code Injection (CVE-ID: CVE-2023-29402)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation within the cgo go command when building code that contains directories with newline characters in their names. A remote attacker can pass specially crafted input to the cgo command at build time and potentially compromise the system.

Modules which are retrieved using the go command, i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off, may be affected).

3) Code Injection (CVE-ID: CVE-2023-29404)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists within Go runtime when running "go get" on a malicious module, or when running any other
command which builds untrusted code.A remote attacker can inject and execute arbitrary code on the target system at build time when using cgo.

4) Code Injection (CVE-ID: CVE-2023-29405)

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists within Go runtime when running "go get" on a malicious module, or when running any other
command which builds untrusted code.A remote attacker can inject and execute arbitrary code on the target system at build time when using cgo.
