Spreadsheet::ParseExcel Remote Code Execution Vulnerability (CVE-2023-7101)

A local attacker, without authentication, can achieve full data confidentiality loss, arbitrary modification of data, complete denial of service or system unavailability. Federal agencies are required to remediate by 2024-01-23 under CISA BOD 22-01.

This is a Software Vulnerability (CWE-95) (CWE-95) vulnerability in Spreadsheet::ParseExcel Spreadsheet::ParseExcel. Spreadsheet::ParseExcel version 0.65 is a Perl module used for parsing Excel files. Spreadsheet::ParseExcel is vulnerable to an arbitrary code execution (ACE) 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. Exploitation requires local access, low attack complexity, no authentication required, and user interaction required.

Probably yes if any of these apply:

CISA added this CVE to the Known Exploited Vulnerabilities catalog on 2024-01-02 based on evidence of active exploitation in the wild. Federal agencies required to remediate by 2024-01-23.
