CVE-2021-41569: Sas Sas/intrnet

High severity, CVSS 7.5. EPSS: 8% chance of exploitation in the next 30 days.

SAS/Intrnet 9.4 build 1520 and earlier allows Local File Inclusion. The samples library (included by default) in the appstart.sas file, allows end-users of the application to access the sample.webcsf1.sas program, which contains user-controlled macro variables that are passed to the DS2CSF macro. Users can escape the context of the configured user-controllable variable and append additional functions native to the macro but not included as variables within the library. This includes a function that retrieves files from the host OS.

Affected products

• Sas Sas/intrnet: before 9.4 (fixed in 9.4); version 9.4 only
