Blast RADIUS: New Cybersecurity Flaw Exposes Networks to MITM Attacks, Experts Warn
Cybersecurity experts uncovered a vulnerability in the RADIUS protocol, dubbed Blast RADIUS, allowing man-in-the-middle attacks to bypass user authentication. Rated 7.5/10 in severity, this flaw could let attackers access network devices without credentials. The best mitigation? Implement RADIUS over TLS (RadSec). Beware the snoops!
Hot Take:
Looks like RADIUS just got a rude awakening from the 90s! Who would have thought that a decades-old protocol could still cause such a ruckus? Time to patch those network devices, folks, because Blast RADIUS is ready to blow!
Key Points:
- A vulnerability in the RADIUS protocol, identified as CVE-2024-3596, allows for MITM attacks.
- Exploit involves manipulating RADIUS traffic and performing hash cracking to bypass authentication.
- Flaw affects non-EAP authentication methods; protocols like IPSec, TLS, and 802.1x remain safe.
- Successful attack lets an intruder gain access to network devices without correct credentials.
- Mitigation includes implementing RADIUS over TLS (RadSec) and updating firmware.
