AlienVault OTX Vulnerabilities

AlienVault OTX Malware

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.

CVE-2023-7101 is an arbitrary code execution vulnerability identified in version 0.65 of the Perl module Spreadsheet::ParseExcel, authored by Douglas Wilson. The module is designed to parse Microsoft Excel files, specifically extracting data from spreadsheets. The vulnerability stems from improper neutralization of directives in dynamically evaluated code (CWE-95), where Number format strings embedded in Excel files are passed without validation into a string-type eval function. This unsafe eval usage allows an attacker to craft malicious Excel files containing specially formatted Number strings that, when parsed, execute arbitrary Perl code on the host system. The vulnerability requires user interaction, as the victim must open or process the malicious Excel file using the vulnerable module. The CVSS v3.1 score is 7.8 (high), reflecting local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The impact affects confidentiality, integrity, and availability (all high). No patches or fixes are currently linked, and no known exploits have been reported in the wild. This vulnerability is particularly dangerous in environments where untrusted Excel files are processed automatically or manually using this Perl module, potentially leading to full system compromise.
