Of these, CVE-2023-3519 has a severity rating of 9.8 out of 10, and it seems that examples of its exploitation have already been confirmed.

The target versions are as follows. Citrix states that version 12.1 has reached its end of life and should be upgraded to a newer version.

・NetScaler ADC and NetScaler Gateway version 13.1-49.13 or later
・NetScaler ADC and NetScaler Gateway versions 13.0-91.13 and 13.0 or later
・NetScaler ADC 13.1-FIPS version 13.1-37.159 or later

According to Bleeping Computer, a security-related news site, in early July 2023, someone wrote on a forum for hackers that ``Citrix ADC version 13.1 build 48.47 and up had a zero-day vulnerability that allowed remote code execution.'' So, Citrix said that it was working on creating a correction patch before publishing the problem triggered by this writing. Citrix strongly recommends updating to a fixed version that addresses the zero-day vulnerability in question.

In December 2022, Citrix ADC and Citrix Gateway were confirmed to have vulnerabilities that could allow remote execution of arbitrary code, and we called for an immediate update.

In July 2023, Adobe ColdFusion discovered a security function bypass vulnerability ' CVE-2023-29298 ' and a vulnerability ' CVE-2023-29300 ' that allowed arbitrary code execution, and released a patch. It was just The CVE-2023-38203 discovered this time is a vulnerability similar to CVE-2023-29300, and a new patch was distributed just three days after the distribution of the previous patch.
