Hackers now exploit critical Roundcube flaw in code injection attacks
BLUF
Active exploitation of a patched Roundcube vulnerability requires immediate patching.
NEWS
The Canadian Centre for Cyber Security warns that attackers are leveraging a high-severity code injection flaw in Roundcube Webmail originally fixed in May. This indicates that unpatched systems are currently at risk of compromise despite the availability of a fix.
Why I Care
Unpatched email servers can lead to data theft, unauthorized access, and lateral movement within networks. Any organization hosting Roundcube Webmail is vulnerable until updated.
Next Steps
System administrators should apply the May security patch immediately and verify installation across all instances. Security teams should monitor logs for signs of exploitation attempts while prioritizing this update above non-critical tasks.
