CVE-2024-0219: CWE-269 Improper Privilege Management in Progress Software Telerik JustDecompile
In Telerik JustDecompile versions prior to 2024 R1, a privilege elevation vulnerability has been identified in the applications installer component. In an environment where an existing Telerik JustDecompile install is present, a lower privileged user has the ability to manipulate the installation package to elevate their privileges on the underlying operating system.
AI Analysis
Technical Summary
CVE-2024-0219 is a high-severity privilege escalation vulnerability affecting Progress Software's Telerik JustDecompile versions prior to 2024 R1, specifically identified in the installer component of the application. The vulnerability arises due to improper privilege management (CWE-269) during the installation or update process. In environments where Telerik JustDecompile is already installed, a user with limited privileges can manipulate the installation package to escalate their privileges on the underlying operating system. This manipulation could allow the lower privileged user to gain higher-level access, potentially administrative rights, thereby compromising system confidentiality, integrity, and availability. The CVSS 3.1 base score of 7.8 reflects a high severity, with the vector indicating that the attack requires local access (AV:L), high attack complexity (AC:H), low privileges (PR:L), no user interaction (UI:N), and scope change (S:C) with high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no known exploits are currently reported in the wild, the vulnerability's nature makes it a significant risk, especially in multi-user environments or shared systems where users have different privilege levels. The lack of a patch link suggests that a fix may not yet be publicly available, emphasizing the need for immediate mitigation steps to prevent exploitation.
Potential Impact
For European organizations, this vulnerability poses a substantial risk, particularly in enterprises and development environments where Telerik JustDecompile is used for .NET assembly decompilation and analysis. Successful exploitation could allow malicious insiders or compromised low-privilege accounts to gain administrative control over affected systems. This could lead to unauthorized access to sensitive data, installation of persistent malware, disruption of critical services, and lateral movement within corporate networks. Given the high impact on confidentiality, integrity, and availability, organizations could face data breaches, operational downtime, and compliance violations under regulations such as GDPR. The risk is heightened in sectors with stringent security requirements like finance, healthcare, and government institutions across Europe. Additionally, the vulnerability's requirement for local access limits remote exploitation but does not eliminate risk in environments with shared workstations or insufficient access controls.
Mitigation Recommendations
European organizations should immediately audit their environments to identify installations of Telerik JustDecompile, especially versions prior to 2024 R1. Until an official patch is released, organizations should implement strict access controls to limit who can execute or modify the installer and related files. Employ application whitelisting to prevent unauthorized execution of modified installers. Use endpoint protection solutions to monitor and block suspicious installer manipulations. Enforce the principle of least privilege rigorously, ensuring users do not have unnecessary local privileges that could facilitate exploitation. Regularly review and harden user permissions on systems where Telerik JustDecompile is installed. Consider isolating or restricting the use of Telerik JustDecompile to dedicated, secure workstations. Monitor system logs for unusual installation or privilege escalation activities. Finally, maintain close communication with Progress Software for updates and apply patches promptly once available.
