The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does
not validate or incorrectly validates that the input has the
properties that are required to process the data safely and
correctly. Impacted is availability. CVE summarizes:
Google V8 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters, as demonstrated by attacks against Node.js.
The weakness was disclosed 12/29/2011 as confirmed advisory (CERT.org). The advisory is shared for download at kb.cert.org. This vulnerability is handled as CVE-2011-5037 since 12/29/2011. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 11/28/2021).
The vulnerability scanner Nessus provides a plugin with the ID 57552 (FreeBSD : Multiple implementations -- DoS via hash algorithm collision (91be81e7-3fea-11e1-afc7-2c4138874f7d)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 12109.
