CVE-2025-28228
Published: 18 April 2025
Summary
CVE-2025-28228 is a high-severity Insufficiently Protected Credentials (CWE-522) vulnerability in Electrolink Fm\/Dab\/Tv Transmitter Web Management System. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked in the top 9.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
A credential exposure vulnerability affects Electrolink 500W, 1kW, and 2kW Medium DAB Transmitter systems running Web firmware versions v01.09, v01.08, and v01.07 together with Display firmware v1.4 and v1.2. The flaw, tracked as CVE-2025-28228 and assigned CWE-522, permits retrieval of credentials stored in plaintext and carries a CVSS 3.1 score of 7.5 reflecting network-accessible exploitation without authentication.
An unauthenticated remote attacker can directly request the exposed credential data over the network, obtaining valid login material that can be used to access the transmitter's management interface and any associated functions. The two public references consist of a GitHub repository containing the researcher's technical notes; no vendor advisory or patch information is included in the supplied data. The associated EPSS score remains low, with a current value of 0.0611 and a peak of 0.0645.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Training instructs users on protecting credentials from disclosure or unauthorized access.
Training records for security awareness and role-based training verify education on credential protection practices, tangibly reducing risks from mishandling or exposing credentials.
Protecting authenticator content from unauthorized disclosure and modification while requiring protective controls addresses insufficiently protected credentials.
Rules of behavior include credential protection and non-sharing requirements, reducing exposure of insufficiently protected credentials.
Terminating or revoking credentials stops use of insufficiently protected or lingering credentials post-termination.
Requiring confidentiality/integrity protection for stored credentials directly mitigates insufficiently protected credentials on disk or in configuration stores.
Credentials or keys delivered out-of-band are not exposed to interception or inadequate protection on the main transport.
