Analysis Summary

CVE-2023-39156 CVSS:4.3

Jenkins Bazaar Plugin is vulnerable to cross-site request forgery, caused by improper validation of user-supplied input. By persuading an authenticated user to visit a malicious Web site, a remote attacker could send a malformed HTTP request to delete previously created Bazaar SCM tags. An attacker could exploit this vulnerability to perform cross-site scripting attacks, Web cache poisoning, and other malicious activities.

CVE-2023-39155 CVSS:4.3

Jenkins Chef Identity Plugin could allow a remote authenticated attacker to obtain sensitive information, caused by the storage of user.pem key in plain-text in the global configuration file. By gaining access to the configuration file, an attacker could exploit this vulnerability to obtain user.pem key information, and use this information to launch further attacks against the affected system.

CVE-2023-39154 CVSS:4.2

Jenkins Qualys Web App Scanning Connector Plugin could allow a remote authenticated attacker to obtain sensitive information, caused by improper permission validation in several HTTP endpoints. By sending a specially crafted HTTP request, an attacker could exploit this vulnerability to obtain credentials information stored in Jenkins, and use this information to launch further attacks against the affected system.

CVE-2023-3442 CVSS:4.2

Jenkins ServiceNow DevOps Plugin could allow a remote authenticated attacker to bypass security restrictions, caused by improper permission validation. By sending a specially crafted request, an attacker could exploit this vulnerability to connect to an attacker-specified HTTP server.
