Title: Netscript Remote Code Execution Vulnerability
Severity: HIGH
Description:
Netscript is a program designed to allow simple, fast TCP socket scripting. Based on a word substitution ruleset, simple socket based applications may be rapidly developed, and common tasks automated.
The flags -H and -D may be used to display information in hexadecimal or decimal notation, instead of by character. When the remote system sends high valued data, such as 0xFF, memory may be corrupted in a manner that may allow for an attacker to take control over process execution. This situation is dependent on the specific ruleset being used by netscript, which may make it difficult to exploit.
Earlier versions of netscript may also be vulnerable.
Affected Products:
- v9 netscript 1.6.0
- v9 netscript 1.6.1
- v9 netscript 1.6.2
- v9 netscript 1.6.3
- v9 netscript 1.6.4
