Detailsinfo

A vulnerability classified as critical has been found in IBM Informix JDBC Driver 4.10/4.50 (Information Management Software). Affected is an unknown code block of the component JNDI Handler. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

IBM Informix JDBC Driver 4.10 and 4.50 is susceptible to remote code execution attack via JNDI injection when driver code or the application using the driver do not verify supplied LDAP URL in Connect String. IBM X-Force ID: 249511.
