CVE-2022-45693: Jettison Out-of-bounds Write vulnerability

Background

The Jettison package, specifically versions before v1.5.2, is an open-source library for JSON processing in Java. It provides functionality for converting Java objects to JSON and vice versa. Jettison is commonly used in Maven projects and can be identified by the package name 'org.codehaus.jettison:jettison'. This vulnerability affects the map parameter and can lead to a stack overflow. Attackers can exploit this vulnerability to cause a Denial of Service (DoS) by providing a crafted string.

Vulnerability Detail

The Jettison Out-of-bounds Write vulnerability (CVE-2022-45693) arises from a stack overflow in Jettison versions prior to v1.5.2. This vulnerability can be triggered by manipulating the map parameter. By exploiting this vulnerability, an attacker can cause a Denial of Service (DoS) attack by supplying a specially crafted string. The impact of this vulnerability can result in the affected application becoming unresponsive or crashing. The Common Vulnerabilities and Exposures (CVE) identifier for this vulnerability is CVE-2022-45693. The vulnerability has been assigned a CVSSv3 score of 7.5, indicating a high severity level.

Workaround

As a workaround, if upgrading to the fixed version is not immediately feasible, developers can consider implementing input validation and sanitization for the map parameter. By carefully validating and sanitizing user-supplied input, the risk of exploitation can be mitigated. Here is an example of how input validation can be performed in Java:

String mapParam = request.getParameter("map");

if (mapParam != null && !mapParam.isEmpty()) {
    // Perform input validation and sanitization
    // ... (code omitted for brevity)
}

It is important to note that this workaround is not a substitute for upgrading to the fixed version, as it only reduces the risk rather than eliminating it.

Conclusion

The Jettison Out-of-bounds Write vulnerability (CVE-2022-45693) in versions prior to v1.5.2 can be exploited to cause a Denial of Service (DoS) attack. To mitigate this vulnerability, it is crucial to upgrade the Jettison package to version 1.5.2 or later. Developers can also consider implementing input validation and sanitization for the map parameter as a temporary workaround.
