Netscape Navigator URI NULL byte filtering command execution
| netscape-uri-null-command-execution (38322) |  High Risk |
Description:
Netscape Navigator could allow a remote attacker to execute arbitrary commands on the system, caused by improper filtering of encoded NULL byte characters (%00) in certain Uniform Resource Identifiers (URIs), including the mailto, nntp, news, snews, and telnet protocol handlers on Microsoft Windows systems. By persuading a victim to visit a specially-crafted Web page that calls one of the vulnerable protocol handlers, a remote attacker could exploit this vulnerability to inject and execute arbitrary shell commands on the system.
Platforms Affected:
- Netscape, Navigator 9.0b2
Remedy:
Upgrade to the latest version of Netscape Navigator (9.0.0.3 or later), available from the Netscape Web site. See References.
Consequences:
Gain Access
