    CVE-2020-7776 (GCVE-0-2020-7776)

    Vulnerability from nvd – Published: 2020-12-09 16:45 – Updated: 2024-09-16 19:39
    VLAI
    Title
    Cross-site Scripting (XSS)
    Summary
    This affects the package phpoffice/phpspreadsheet from 0.0.0. The library is vulnerable to XSS when creating an html output from an excel file by adding a comment on any cell. The root cause of this issue is within the HTML writer where user comments are concatenated as part of link and this is returned as HTML. A fix for this issue is available on commit 0ed5b800be2136bcb8fa9c1bdf59abc957a98845/master branch.

    CVE-2019-12331 (GCVE-0-2019-12331)

    Vulnerability from nvd – Published: 2019-11-07 14:03 – Updated: 2024-08-04 23:17
    VLAI
    Summary
    PHPOffice PhpSpreadsheet before 1.8.0 has an XXE issue. The XmlScanner decodes the sheet1.xml from an .xlsx to utf-8 if something else than UTF-8 is declared in the header. This was a security measurement to prevent CVE-2018-19277 but the fix is not sufficient. By double-encoding the the xml payload to utf-7 it is possible to bypass the check for the string ‚<!ENTITY‘ and thus allowing for an xml external entity processing (XXE) attack.
    Severity
    No CVSS data available.

    Title
    PhpSpreadsheet HTML writer is vulnerable to Cross-Site Scripting via style information
    Summary
    PHPSpreadsheet is a pure PHP library for reading and writing spreadsheet files. In affected versions `\PhpOffice\PhpSpreadsheet\Writer\Html` doesn't sanitize spreadsheet styling information such as font names, allowing an attacker to inject arbitrary JavaScript on the page. As a result an attacker may used a crafted spreadsheet to fully takeover a session of a user viewing spreadsheet files as HTML. This issue has been addressed in release version 2.1.0. All users are advised to upgrade. There are no known workarounds for this vulnerability.

    CVE-2019-12331 (GCVE-0-2019-12331)

    Vulnerability from cvelistv5 – Published: 2019-11-07 14:03 – Updated: 2024-08-04 23:17
    VLAI
    Summary
    PHPOffice PhpSpreadsheet before 1.8.0 has an XXE issue. The XmlScanner decodes the sheet1.xml from an .xlsx to utf-8 if something else than UTF-8 is declared in the header. This was a security measurement to prevent CVE-2018-19277 but the fix is not sufficient. By double-encoding the the xml payload to utf-7 it is possible to bypass the check for the string ‚<!ENTITY‘ and thus allowing for an xml external entity processing (XXE) attack.
    Severity
    No CVSS data available.
