SCA: security update for phpoffice/phpspreadsheet (GHSA-6hwr-6v2f-3m88)

high Tenable Self-Hosted Container Security Plugin ID 411482

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - PHPSpreadsheet is a pure PHP library for reading and writing spreadsheet files. The security scanner
 responsible for preventing XXE attacks in the XLSX reader can be bypassed by slightly modifying the XML
 structure, utilizing white-spaces. On servers that allow users to upload their own Excel (XLSX) sheets,
 Server files and sensitive information can be disclosed by providing a crafted sheet. The security scan
 function in src/PhpSpreadsheet/Reader/Security/XmlScanner.php contains a flawed XML encoding check to
 retrieve the input file's XML encoding in the toUtf8 function. The function searches for the XML encoding
 through a defined regex which looks for `encoding="*"` and/or `encoding='*'`, if not found, it defaults to
 the UTF-8 encoding which bypasses the conversion logic. This logic can be used to pass a UTF-7 encoded XXE
 payload, by utilizing a whitespace before or after the = in the attribute definition. Sensitive
 information disclosure through the XXE on sites that allow users to upload their own excel spreadsheets,
 and parse them using PHPSpreadsheet's Excel parser. This issue has been addressed in release versions
 1.29.1, 2.1.1, and 2.3.0. All users are advised to upgrade. There are no known workarounds for this
 vulnerability. (CVE-2024-45293)
