Summary

perl-Spreadsheet-ParseExcel security update

Details

The Spreadsheet::ParseExcel module can be used to read information from an Excel 95-2003 file.

Security Fix(es):

Spreadsheet::ParseExcel version 0.65, a Perl module for parsing Excel files, is vulnerable to arbitrary code execution (ACE) due to passing unvalidated input from a file into a string-type eval. The issue specifically arises from the evaluation of Number format strings (distinct from printf-style format strings) within the Excel parsing logic.(CVE-2023-7101)

Severity

7.8 (High)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
