The version of Siemens JT2Go installed on the remote Windows hosts is prior to 13.1.0.2. It is, therefore, affected by multiple vulnerabilities, including the following:
Affected applications lack proper validation of user-supplied data when parsing ASM files. This could lead to pointer dereferences of a value obtained from untrusted source. An attacker could leverage this vulnerability to execute code in the context of the current process. (CVE-2020-26991)
Affected applications lack proper validation of user-supplied data when parsing of PAR files. This could result in a memory access past the end of an allocated buffer. An attacker could leverage this vulnerability to leak information. (CVE-2020-26999)
Affected applications lack proper validation of user-supplied data when parsing of PAR files. This could result in a stack based buffer overflow. An attacker could leverage this vulnerability to execute code in the context of the current process. (CVE-2020-27001)
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
