Description

This security bulletin contains information about 7 secuirty vulnerabilities.


1) Cross-site scripting (CVE-ID: CVE-2023-24539)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when handling angle brackets in CSS context. A remote attacker can inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


2) Cross-site scripting (CVE-ID: CVE-2023-29400)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data when processing HTML attributes. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-29403)

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

The vulnerability exists within Go runtime due to application allows to execute setuid/setgid binaries without any restrictions. An attacker with ability to control the application flow can execute arbitrary code on the system with elevated privileges.


4) 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.


5) 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).


6) 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.

7) 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.
