VAR-200010-0084
Vulnerability from variot - Updated: 2023-12-18 14:07Buffer overflow in SGI Omron WorldView Wnn allows remote attackers to execute arbitrary commands via long JS_OPEN, JS_MKDIR, or JS_FILE_INFO commands. A remote buffer overflow exists in the Asian language servers portion of a number of different implementations of Wnn. It has been reported that only systems that have WorldView Japanese, Korean, and Chinese installed are vulnerable to this issue. Wnn is a Kana-Kanji translation system, most commonly used for foreign language support in Unix systems. An overflow exists when the server receives a long string with a Wnn command, such as JS_OPEN, JS_MKDIR or JS_FILE_INFO included. By creating a buffer containing machine executable code, it is possible to cause a remote system running the jserver daemon to execute arbitrary commands as the user the daemon is running as. This is frequently root. It is a server-client application, and the Jserver part acts as the server side, providing translation services for clients. Some versions of Wnn have a remote buffer overflow vulnerability. Carefully constructed strings leading to overflows have the potential to execute arbitrary commands with privileges owned by the Jserver, usually root
