CVE-2025-48930 is a vulnerability identified in the TeleMessage service, classified under CWE-316, which pertains to the cleartext storage of sensitive information in memory. This vulnerability means that certain sensitive data handled by the TeleMessage service is stored in an unencrypted form in the system's memory. Although the vulnerability does not indicate direct exploitation through network vectors, the cleartext data in memory could be exposed to an adversary who has local access or can leverage other attack vectors to read memory contents. The CVSS v3.1 score for this vulnerability is 2.8, which is considered low severity. The vector string (AV:L/AC:H/PR:L/UI:N/S:C/C:L/I:N/A:N) indicates that the attack requires local access (AV:L), high attack complexity (AC:H), low privileges (PR:L), no user interaction (UI:N), and the scope is changed (S:C). The impact on confidentiality is low (C:L), with no impact on integrity (I:N) or availability (A:N). The vulnerability does not have any known exploits in the wild and no patches have been linked yet. The affected version is listed as "0," which likely indicates an unspecified or initial version of the TeleMessage service. The core risk lies in potential memory scraping or local attacks that could reveal sensitive information, which might include credentials, tokens, or other confidential data stored in memory in cleartext. This could facilitate further attacks if an adversary gains local access or exploits other vulnerabilities to read memory contents.

For European organizations using the TeleMessage service, this vulnerability poses a limited but non-negligible risk. The primary concern is the potential exposure of sensitive information if an attacker gains local access to systems running the vulnerable TeleMessage service. This could occur through insider threats, compromised user accounts with local access, or chained exploits that escalate privileges to read memory. While the direct impact on confidentiality is low and there is no impact on integrity or availability, the exposure of sensitive data could lead to secondary attacks such as credential theft or unauthorized access to other systems. Organizations in sectors with high regulatory requirements for data protection, such as finance, healthcare, and government, may face compliance risks if sensitive data is exposed. However, the requirement for local access and high attack complexity reduces the likelihood of widespread exploitation. The lack of known exploits in the wild further limits immediate risk, but organizations should remain vigilant and monitor for updates or patches from TeleMessage.

Given the nature of this vulnerability, European organizations should implement the following specific mitigations: 1) Restrict and monitor local access to systems running the TeleMessage service, ensuring only authorized personnel have access. 2) Employ memory protection mechanisms such as Address Space Layout Randomization (ASLR) and Data Execution Prevention (DEP) to make memory scraping more difficult. 3) Use endpoint detection and response (EDR) tools to detect unusual memory access patterns or attempts to read process memory. 4) Regularly audit and harden user privileges to minimize the risk of privilege escalation that could lead to memory exposure. 5) Isolate critical TeleMessage service instances in secure environments or virtual machines with strict access controls. 6) Engage with TeleMessage vendor support to obtain patches or updates as they become available and apply them promptly. 7) Implement encryption for sensitive data at rest and in transit within the TeleMessage ecosystem to reduce the impact if memory contents are exposed. 8) Conduct regular security training for staff to recognize and report suspicious activity that could lead to local compromise.
