Medium
| Vector | AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Janino versions 3.1.9 and earlier
Description
The issue allows for denial of service (DOS) attacks when using the
evaluator.guess parameter name method. If the parser runs on user-supplied input, an attacker could supply content that causes the parser to crash due to a stack overflow. It is noted that this is disputed by multiple parties because Janino is not intended for use with untrusted input.Recommendations
For Janino versions 3.1.9 and earlier, as a temporary workaround, consider restricting the use of the
evaluator.guess parameter name method until a patch is available. Avoid running the parser on user-supplied input to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
