CVE-2013-7140

Status: ModifiedMedium (4)—

XML External Entity (XXE) vulnerability in the CalDAV interface in Open-Xchange (OX) AppSuite 7.4.1 and earlier allows remote authenticated users to read portions of arbitrary files via vectors related to the SAX builder and the WebDAV interface. NOTE: this issue has been labeled as both absolute path traversal and XXE, but the root cause may be XXE, since XXE can be exploited to conduct absolute path traversal and other attacks.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
