Linux Distros Unpatched Vulnerability : CVE-2017-16790

medium Nessus Plugin ID 256002

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- An issue was discovered in Symfony before 2.7.38, 2.8.31, 3.2.14, 3.3.13, 3.4-BETA5, and 4.0-BETA5. When a form is submitted by the user, the request handler classes of the Form component merge POST data and uploaded files data into one array. This big array forms the data that are then bound to the form. At this stage there is no difference anymore between submitted POST data and uploaded files. A user can send a crafted HTTP request where the value of a FileType is sent as normal POST data that could be interpreted as a local file path on the server-side (for example, file:///etc/passwd). If the application did not perform any additional checks about the value submitted to the FileType, the contents of the given file on the server could have been exposed to the attacker. (CVE-2017-16790)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
