Spreadsheet::ParseExcel RCE (CVE-2023-7101)

high Nessus Plugin ID 197297

Language:

Synopsis

The Perl module is vulnerable to an remote code execution vulnerability.

Description

According to its self-reported version number, the Spreadsheet::ParseExcel perl module is vulnerable to a remote code execution vulnerability due to passing unvalidated input from a file into a string-type “eval”. Specifically, the issue stems from the evaluation of Number format strings (not to be confused with printf-style format strings) within the Excel parsing logic.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Spreadsheet::ParseExcel version 0.66 or later.
