Authenticated code execution via jdbcUrl deserialization
Published Jun 21, 2026 · Updated Jun 21, 2026
Deserialization in Zhilink ADP Application Developer Platform 1.0.0 allows remote authenticated users to execute code via jdbcUrl. The testConnection endpoint processes the attacker-controlled jdbcUrl argument through an untrusted-data deserialization path without adequate input validation. Low-privilege access and network reachability are required; successful exploitation executes code in the application server's security context.
