Spreadsheet::ParseExcel Remote Code Execution Vulnerability
Spreadsheet::ParseExcel - Spreadsheet::ParseExcel · Listed in the CISA KEV since 2024-01-02. This indicates confirmed attacks in production environments.
Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CVE-2023-7101
HighCVSS 7.8KEVSummary
Spreadsheet::ParseExcel version 0.65 is a Perl module used for parsing Excel files. It 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 within the Excel parsing logic.
Risk Assessment
An attacker could provide a malicious Excel file that, when processed by an application using Spreadsheet::ParseExcel, leads to arbitrary code execution in the application's context.
Recommendation
Update Spreadsheet::ParseExcel to a patched version or avoid processing untrusted Excel files.

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.
