CVE-2022-34793: 
Java vulnerability analysis and mitigation

Jenkins Recipe Plugin version 1.2 and earlier contains an XML External Entity (XXE) vulnerability identified as CVE-2022-34793. The vulnerability was discovered in June 2022 and affects the plugin's XML parser configuration. The issue is part of a larger set of vulnerabilities (including CSRF and missing permission checks) that affect the Recipe Plugin (Jenkins Advisory).

The vulnerability stems from the plugin's failure to configure its XML parser to prevent XML external entity (XXE) attacks. When processing XML responses from HTTP requests, the plugin does not implement proper XML parsing security controls. This vulnerability has been rated as High severity. The issue allows attackers with Overall/Read permission to send an HTTP request to an attacker-specified URL and parse the response as XML, potentially leading to the extraction of secrets from the Jenkins controller or server-side request forgery (Jenkins Advisory).

The vulnerability can be exploited to extract sensitive information from the Jenkins controller through XXE attacks. Additionally, attackers can leverage this vulnerability for server-side request forgery (SSRF). The plugin also allows users to export the full configuration of jobs as part of a recipe, exposing job configuration XML data to users with Item/Read permission, including encrypted values of secrets that would normally be redacted (Jenkins Advisory).

As of the publication of the security advisory on June 30, 2022, no fixes are available for this vulnerability in the Recipe Plugin. Users are advised to assess their risk and consider removing the plugin if the vulnerability poses a significant security concern (Jenkins Advisory).
