CVE-2008-6504

42
FAUCET Score

CVE-2008-6504 describes a critical vulnerability in the ParametersInterceptor component of OpenSymphony XWork versions 2.0.x before 2.0.6 and 2.1.x before 2.1.2, which is notably used in Apache Struts. This flaw allows remote attackers to bypass security restrictions by using a specially crafted pound sign (#) representation, enabling them to execute arbitrary Object-Graph Navigation Language (OGNL) statements and modify server-side context objects. The vulnerability carries a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:N/I:P/A:N), indicating it is network-exploitable with low attack complexity, requiring no authentication, and primarily leading to partial integrity impact. Its EPSS score of 0.65118 and FAUCET Risk Score of 98/100 suggest a high likelihood of exploitation and significant risk. While not listed on the KEV catalog or Hot List, exploit code is publicly available via ExploitDB (EDB-32564). Despite the availability of exploit code, there is no recorded community discussion or media coverage, which is typical for a significant portion of CVEs.
