CVE-2024-3742
Published: 18 April 2024
Summary
CVE-2024-3742 is a high-severity Cleartext Storage of Sensitive Information (CWE-312) vulnerability in Cisa (inferred from references). Its CVSS base score is 8.7 (High).
Operationally, ranked in the top 7.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
CVE-2024-3742 is a clear-text credential storage vulnerability affecting Electrolink transmitters and is tracked under CWE-312. The affected devices expose sensitive authentication material that can be read directly from storage, producing a CVSS 4.0 score of 8.7 with network attack vector and no required privileges or user interaction.
An unauthenticated remote attacker can retrieve the stored credentials and use them to gain access to the transmitter. Because the credentials are held in plaintext, no additional cryptographic bypass or privilege escalation is needed to obtain valid login material.
CISA has released ICS advisory ICSA-24-107-02 that addresses the issue for industrial control system operators.
The associated EPSS score rose from a low baseline to a peak of 0.1081 before receding to the current value of 0.0826, indicating that exploitation interest increased after public disclosure.

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 on secure data handling discourages cleartext storage of sensitive information.
Data action mapping can detect storage actions that leave sensitive information in cleartext.
Configuration policies can mandate secure storage methods to avoid cleartext storage of sensitive information.
Policy requires protection measures such as encryption for sensitive data stored on media, preventing cleartext exposure.
Key-management policy requires protected storage of key material, preventing cleartext storage of sensitive cryptographic keys.
Requiring confidentiality protection for information at rest eliminates cleartext storage of sensitive data on persistent media.
Reduces cleartext storage of sensitive data when OPSEC identifies and mandates protection of key information artifacts.
