Summary

CVE-2024-25735 is a critical-severity Cleartext Transmission of Sensitive Information (CWE-319) vulnerability in Wyrestorm Apollo Vx20 Firmware. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Network Sniffing (T1040); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-8 (Transmission Confidentiality and Integrity) — 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-2024-25735 is an information disclosure vulnerability affecting WyreStorm Apollo VX20 devices running firmware versions prior to 1.3.58. The flaw permits remote retrieval of cleartext passwords by issuing an unauthenticated GET request to the SoftAP /device/config endpoint and is tracked under CWE-319 for cleartext transmission of sensitive information, resulting in a CVSS 3.1 base score of 9.1.

Unauthenticated attackers with network access can exploit the issue without user interaction to obtain administrative credentials, enabling subsequent unauthorized access that impacts confidentiality and integrity.

Public references including Packet Storm and Full Disclosure list the affected devices and the version threshold for remediation, indicating that upgrading to firmware 1.3.58 or later addresses the exposure. The associated EPSS score has remained consistently high near 0.90 with only minor variation between its recorded peak and current value.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SC-8 directly requires protecting confidentiality of transmitted information, which structurally eliminates cleartext transmission of sensitive data.

PR.DS-02 full match
prevents

Encryption of data-in-transit directly prevents cleartext transmission while the control also addresses integrity and availability.

prevents

Specifying encryption and other security technology for network services prevents transmission of sensitive information in cleartext over potentially untrusted channels.

prevents

Mandating cryptographic protection and stronger authentication on public networks stops the transmission of plaintext sensitive information.

mitigates

Specifying communications-security requirements and secure remote-access methods (including encryption expectations) prevents the transmission of sensitive data in cleartext over home or public networks.

mitigates

Armoured conduits, electromagnetic shielding and locked enclosures make passive eavesdropping on unencrypted traffic traversing the cables more difficult, mitigating exposure of sensitive data in transit.
