Citrix ADC Gateway - Remote Code Execution CVE-2023-3519

Citrix ADC Gateway is vulnerable to CVE-2023-3519, a Remote Code Execution vulnerability. The root cause of this vulnerability is a stack overflow caused by the inexistence of any bound checks when a SAML payload is parsed into a struct containing the relevant details. This vulnerability allows an unauthenticated remote attacker to gain Remote Code Execution.

The risk exists that an unauthenticated remote attacker could gain Remote Code Execution access which will result in a fully compromised server through which they could steal confidential information, install ransomware, or pivot to the internal network.

Sniper can gain unauthenticated Remote Code Execution on the target system and extract multiple artefacts as evidence.

Update Citrix ADC Gateway to the latest version available.
