EspoCRM: Blind SQL injection via streamAttachments where-clause complex expression
CVSS Score
7.6
EPSS Score
0.0%
EPSS Percentile
0th
EspoCRM is an open source customer relationship management application. From 8.1.0 until 9.3.8, an authenticated non-administrator can submit a crafted where parameter to the GET entity streamAttachments endpoint because that query path permits complex expressions. Boolean-based blind SQL injection can extract arbitrary database information, including active administrator session tokens, and can enable full privilege escalation. This issue is fixed in version 9.3.8.
