Overview
CVE-2025-13295 is a high-severity vulnerability affecting Argus Technology Inc.’s BILGER software. This vulnerability allows an attacker to insert sensitive information into data that is sent by the system. Specifically, the issue arises from the ability to influence and choose the message identifier. This affects versions of BILGER prior to 2.4.9.
Technical Details
The vulnerability stems from insufficient input validation and sanitization related to the message identifier within the BILGER application. An attacker can leverage this flaw to inject arbitrary data into the message identifier field. This injected data can then be transmitted alongside legitimate data, potentially exposing sensitive information that should have remained confidential.
The ability to “Choose Message Identifier” allows a malicious actor to craft payloads containing sensitive data and associate it with a valid message, effectively smuggling unauthorized information through the system.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) score for CVE-2025-13295 is 7.5, indicating a high severity vulnerability. This score reflects the potential for significant impact on confidentiality and integrity.
- Base Score: 7.5 (High)
- Vector String: [Please consult the NVD or FIRST for the specific CVSS vector string. Example: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N – This is an example only and should be verified]
Possible Impact
The exploitation of CVE-2025-13295 can lead to severe consequences, including:
- Data Breach: Sensitive information could be exfiltrated from the system.
- Compliance Violations: Exposure of protected data (e.g., PII, PHI) can result in regulatory penalties.
- Reputational Damage: A successful attack could significantly damage the reputation of organizations using the affected BILGER software.
- System Compromise: In some scenarios, the inserted data could be used to further compromise the system or other connected systems.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-13295, it is crucial to take the following steps:
- Upgrade BILGER: Upgrade to version 2.4.9 or later. This version contains the necessary fix to address the vulnerability.
- Input Validation: Implement robust input validation and sanitization measures to prevent the injection of arbitrary data into the message identifier field. This should be part of a defense-in-depth strategy, even after patching.
- Network Segmentation: Isolate the BILGER system from other critical systems to limit the potential impact of a successful attack.
- Monitoring and Logging: Implement comprehensive monitoring and logging to detect and respond to suspicious activity. Pay particular attention to anomalies in message identifiers.
