Organizations big and small are once again scrambling to patch critical vulnerabilities that are already under active exploitation and cause the kind of breaches coveted by ransomware actors and nation-state spies.
The exploited vulnerabilities-one in Adobe ColdFusion and the other in various Citrix NetScaler products-allow for the remote execution of malicious code. Citrix on Tuesday patched the vulnerabilities, but not before threat actors exploited them. The most critical vulnerability, tracked as CVE-2023-3519, lurks in Citrix's NetScaler ADC and NetScaler Gateway products. It carries a severity rating of 9.8 out of a possible 10 because it allows hackers to execute code remotely with no authentication required.
This product line is a popular target for attackers of all skill levels, and we expect that exploitation will increase quickly," researchers from Rapid7, the security firm that detected the attacks, warned Tuesday.
