Summary

Kentico 9.0 through 11.0 has a stack-based buffer overflow via the SqlName, SqlPswd, Database, UserName, or Password field in a SilentInstall XML document. NOTE: the vendor disputes this issue because neither a buffer overflow nor a crash can be reproduced; also, reading XML documents is implemented exclusively with managed code within the Microsoft .NET Framework

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
