The U.S. Cybersecurity and Infrastructure Safety Company (CISA) has added a crucial safety flaw impacting Jenkins to its Identified Exploited Vulnerabilities (KEV) catalog, following its exploitation in ransomware assaults.
The vulnerability, tracked as CVE-2024-23897 (CVSS rating: 9.8), is a path traversal flaw that might result in code execution.
“Jenkins Command Line Interface (CLI) incorporates a path traversal vulnerability that enables attackers restricted learn entry to sure information, which may result in code execution,” CISA mentioned in an announcement.
It was first disclosed by Sonar safety researchers in January 2024 and addressed in Jenkins variations 2.442 and LTS 2.426.3 by disabling the command parser function.
Again in March, Pattern Micro mentioned it uncovered a number of assault situations originating from the Netherlands, Singapore, and Germany, and that it discovered situations the place distant code execution exploits for the flaw have been actively being traded.
In current weeks, CloudSEK and Juniper Networks have revealed a collection of cyber assaults exploiting CVE-2024-23897 within the wild to infiltrate the businesses BORN Group and Brontoo Know-how Options.
The assaults have been attributed to risk actor often called IntelBroker and the RansomExx ransomware gang, respectively.

“CVE-2024-23897 is an unauthenticated LFI vulnerability that enables attackers to learn arbitrary information on the Jenkins server,” CloudSEK mentioned. “This vulnerability arises from improper enter validation, enabling attackers to control particular parameters and trick the server into accessing and displaying the contents of delicate information.”
In gentle of the energetic exploitation of the vulnerability, Federal Civilian Govt Department (FCEB) companies have time until September 9, 2024, to use the fixes and safe their networks in opposition to energetic threats.
