PHPExcel before 1.8.0, as used in ownCloud Server before 5.0.15 and 6.0.x before 6.0.2, does not disable external entity loading in libxml, which allows remote attackers to read arbitrary files, cause a denial of service, or possibly have other impact via an XML External Entity (XXE) attack.

Security readout for executives and security teams

This is a legacy XML parsing flaw in PHPExcel, including affected ownCloud Server versions. A remote attacker could make the application read local files or trigger denial of service if vulnerable parsing is reachable. No active exploitation is cited in the provided sources. Exposure is most likely in legacy PHP applications using PHPExcel before 1.8.0, or ownCloud Server before 5.0.15 or 6.0.2. Risk is higher where untrusted spreadsheet or XML-derived content reaches PHPExcel parsing paths. Prioritize remediation for any internet-facing or externally accessible legacy ownCloud/PHPExcel deployment. The business risk is unauthorized local file disclosure and service disruption, but urgency depends on whether vulnerable parsing paths are reachable. Mitigation focus: Upgrade PHPExcel to 1.8.0 or later where it is still present.; Upgrade ownCloud Server to 5.0.15, 6.0.2, or later as applicable.; Remove or isolate legacy upload/import features that process untrusted spreadsheet content..
