This vulnerability allows remote attackers to execute arbitrary code on affected installations of Arista NG Firewall. Minimal user interaction is required to exploit this vulnerability.\n\nThe specific flaw exists within the processing of the User-Agent HTTP header. The issue results from the lack of proper validation of user-supplied data, which can lead to the injection of an arbitrary script. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-24407.","Arista NG Firewall User-Agent Cross-Site Scripting Remote Code Execution Vulnerability.

The attacker could transfer private information, such as cookies that may include session information, from the victim's machine to the attacker. The attacker could send malicious requests to a web site on behalf of the victim, which could be especially dangerous to the site if the victim has administrator privileges to manage that site. Phishing attacks could be used to emulate trusted web sites and trick the victim into entering a password, allowing the attacker to compromise the victim's account on that web site. Finally, the script could exploit a vulnerability in the web browser itself possibly taking over the victim's machine, sometimes referred to as \"drive-by hacking.\"\nIn many cases, the attack can be launched without the victim even being aware of it. Even with careful users, attackers frequently use a variety of methods to encode the malicious portion of the attack, such as URL encoding or Unicode, so the request looks less suspicious.","Stable","Base","Simple",false,[],{"title":70,"metaDescription":71,"keywords":72,"canonicalUrl":73,"structuredData":74},"What is CVE-2025-2767?
