Comprehensive Technical Analysis of EUVD-2026-9839
1. Vulnerability Assessment and Severity Evaluation
The vulnerability described in EUVD-2026-9839 pertains to an unsafe parsing of OpenMQ's configuration, which allows a remote attacker to read arbitrary files from a MQ Broker's server. This vulnerability is severe due to the potential for unauthorized access to sensitive files and, in some scenarios, the possibility of Remote Code Execution (RCE).
Severity Evaluation:
- Base Score: 9.1 (Critical)
- Base Score Version: CVSS 3.1
- Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H
The CVSS score of 9.1 indicates a critical vulnerability. The vector string highlights the following:
- Attack Vector (AV): Network (N)
- Attack Complexity (AC): Low (L)
- Privileges Required (PR): None (N)
- User Interaction (UI): None (N)
- Scope (S): Unchanged (U)
- Confidentiality (C): High (H)
- Integrity (I): None (N)
- Availability (A): High (H)
This combination suggests that the vulnerability can be exploited remotely with low complexity, requiring no privileges or user interaction, and can result in high impact on confidentiality and availability.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Remote File Reading: An attacker can exploit the unsafe parsing of OpenMQ's configuration to read arbitrary files from the MQ Broker's server. This could include sensitive configuration files, logs, or other critical data.
- Remote Code Execution (RCE): In some scenarios, the vulnerability could be leveraged to execute arbitrary code on the MQ Broker's server, leading to complete system compromise.
Exploitation Methods:
- Configuration Manipulation: An attacker could manipulate the configuration files or send specially crafted requests to the MQ Broker to exploit the unsafe parsing.
- File Path Traversal: By injecting malicious file paths, an attacker could traverse the file system and access unauthorized files.
3. Affected Systems and Software Versions
Affected Systems:
- Product: Eclipse OpenMQ
- Versions: 0 ≤ 6.5.1
All systems running Eclipse OpenMQ versions up to and including 6.5.1 are affected by this vulnerability.
