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, exploitation aligns with the MITRE ATT&CK technique Credentials In Files (T1552.001); ranked in the top 29% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SC-28 (Protection of Information at Rest) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Requiring non-standard deletion or physical destruction of media ensures that sensitive information is not left in cleartext on discarded or repurposed equipment.
Secure deletion of data before device transfer prevents residual sensitive information from remaining in cleartext on storage media that leave organizational control.
Secure deletion of obsolete or temporary copies prevents sensitive data from remaining in cleartext on disk after its intended lifetime.
Substituting real values with hashes or encrypted tokens before storage reduces the quantity of cleartext sensitive information that ends up persisted on disk.
When clear-text sensitive data is detected leaving controlled storage, the control can block the transfer, thereby limiting the exposure that would result from unencrypted storage on external media or cloud services.
By insisting that any retained test copies be stored securely and only for testing, the control reduces the likelihood that clear-text operational data will persist on disk or in backups.
