apollo_vx20: Cleartext Transmission of Sensitive Information
CVE-2024-25735 is a critical-severity cleartext transmission of sensitive information vulnerability in apollo_vx20 from Wyrestorm, with a CVSS 3.1 base score of 9.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.3.58 as the first without the flaw, so updating apollo_vx20 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 50.6% chance of exploitation within 30 days, which is in the top 1.06% of all scored CVEs.
Exploitation in the next 30 days is more likely than not, according to EPSS.
What to do
- Update apollo_vx20 to 1.3.58 or a later version.
- Update Apollo Vx20 Firmware to 1.3.58 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

The underlying weakness: Cleartext Transmission of Sensitive Information
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
How developers prevent this class of flaw
- Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
- When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
- When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
