I can’t say WHY I’m looking at bash script vulnerabilities, but they’ve been around since…well, this Kaspersky article is based upon CVE-2014-6271.
“The “bash bug,” also known as the Shellshock vulnerability, poses a serious threat to all users. The threat exploits the Bash system software common in Linux and Mac OS X systems in order to allow attackers to take potentially take control of electronic devices. An attacker can simply execute system level commands, with the same privileges as the affected services….
“But just imagine that you could not only pass this normal system information to the CGI script, but could also tell the script to execute system level commands. This would mean that – without having any credentials to the webserver – as soon as you access the CGI script it would read your environment variables; and if these environment variables contain the exploit string, the script would also execute the command that you have specified.”
An authorization nightmare as a hostile non-person entity runs amok.
And it’s still a threat, as two recent CVEs attest…and that’s all I’ll say.
