    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.

    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.
