Detailsinfo

A vulnerability classified as problematic has been found in jQuery up to 1.8.1 (JavaScript Library). This affects the function jQuery(strInput). The manipulation as part of a String leads to a cross site scripting vulnerability. CWE is classifying the issue as CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. This is going to have an impact on integrity. The summary by CVE is:

jQuery before 1.9.0 is vulnerable to Cross-site Scripting (XSS) attacks. The jQuery(strInput) function does not differentiate selectors from HTML in a reliable fashion. In vulnerable versions, jQuery determined whether the input was HTML by looking for the '<' character anywhere in the string, giving attackers more flexibility when attempting to construct a malicious payload. In fixed versions, jQuery only deems the input to be HTML if it explicitly starts with the '<' character, limiting exploitability only to attackers who can control the beginning of a string, which is far less common.

The bug was discovered 12/13/2012. The weakness was published 01/19/2018 (Website). The advisory is shared at securityfocus.com. This vulnerability is uniquely identified as CVE-2012-6708 since 01/18/2018. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Technical details and a public exploit are known. MITRE ATT&CK project uses the attack technique T1059.007 for this issue.

The exploit is shared for download at packetstormsecurity.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1862 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 241624 (Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS : jQuery vulnerabilities (USN-7622-1)), which helps to determine the existence of the flaw in a target environment. The commercial vulnerability scanner Qualys is able to test this issue with plugin 13371 (jQuery Prior to 1.9.0 Cross-Site Scripting Vulnerability).

Upgrading to version 1.9.0 eliminates this vulnerability.

The vulnerability is also documented in the databases at Exploit-DB (49708), Tenable (241624) and SecurityFocus (BID 102792†). Similar entries are available at VDB-110197, VDB-110288, VDB-110317 and VDB-111303. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
