Vulnerability Title
Nextcloud: Tables app allows limited SQLi in ORDER BY with malicious sort order argument for Table Views
Source: CVE Program / CVE List V5
Vulnerability Description
Nextcloud is an open source content collaboration platform. From versions 0.9.0 to before 0.9.7, and 1.0.0 to before 1.0.2, a missing sanitization in the Tables app allowed a user with access to the tables app to perform a limited SQL injection in the ORDER BY statement of a query. Compared to normal SQL injections, the ORDER BY is limited to extracting a single bit of information per request or to make the database wait for a given time. This issue has been patched in versions 0.9.7 and 1.0.2.
