Overview<\/strong><\/p>\n

The CVE-2025-21459 is a significant security vulnerability primarily affecting the ML IE parsing per STA profile. This vulnerability can lead to a Transient Denial of Service (DOS) attack, compromising the functionality and potentially the security of affected systems. This matter is of significant concern to organizations and individuals alike due to the potential for system compromise and data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-21459
\nSeverity: High (7.5)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system compromise and data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

ML IE Parsers | All versions prior to patch<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit operates by taking advantage of the vulnerability in ML IE’s parsing of per STA profiles. An attacker can manipulate this weakness to cause a Transient DOS attack, which could temporarily disrupt the functionality of the system. With a successful exploit, the attacker could potentially gain unauthorized access to sensitive data or even take control of the system.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how the vulnerability might be exploited:<\/p>\n

POST \/MLIE\/ParseSTAProfile HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/xml\n<\/code><\/pre>\n
This example demonstrates an HTTP request that, when processed by the vulnerable ML IE parser, results in a Transient DOS attack.
\nIn this example, `malicious_attribute` is an attribute manipulated by the attacker to include a payload that causes a Transient DOS when parsed. This exploit could lead to potential system compromise and data leakage if not promptly mitigated.<\/p>\n","protected":false},"excerpt":{"rendered":"
