The version of Adobe After Effects installed on the remote Windows host is prior to 18.4. It is, therefore, affected by multiple vulnerabilities, including the following:
A vulnerability exists allowing access of memory location after the end of the buffer. An attacker can exploit this to execute arbitrary code on an affected system. (CVE-2021-35996, CVE-2021-36017)
An out-of-bounds write vulnerability exists in Adobe After Effects. An attacker can exploit this to execute arbitrary code on an affected system. (CVE-2021-35993, CVE-2021-35994)
An input validation vulnerability exists in Adobe After Effects. An attacker can exploit this to execute arbitrary code on an affected system. (CVE-2021-35995)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
