Mitsubishi’s MELSEC iQ-F: Locked Out and Lovin’ It – A Hilarious Denial-of-Service Flaw!
Beware of overly enthusiastic password guessers! The MELSEC iQ-F Series vulnerability could leave legitimate users locked out while attackers enjoy unlimited retries. With no fix in sight, use a VPN and firewalls to dodge this denial-of-service debacle. Remember, there’s no such thing as too secure!
Hot Take:
Ah, the joys of technology! The MELSEC iQ-F Series has a lockout mechanism so “secure” that it can deny access to the rightful owners. Who needs hackers when your own system locks you out for your own good? Maybe it’s just a new innovative way to enforce mandatory coffee breaks at work!
Key Points:
- MELSEC iQ-F Series has a denial-of-service vulnerability due to an overly restrictive lockout mechanism.
- The vulnerability has a CVSS v4 score of 6.9, indicating moderate severity.
- No fixed version planned by Mitsubishi Electric; users must implement mitigation strategies.
- Critical infrastructure sectors worldwide are potentially affected.
- Mitigation includes using firewalls, VPNs, and restricting network access.
