Aladdin eSafe Gateway ‘unsafe’
Silly and trivial error
A flaw with a content security product means it could be easily compromised by a maliciously constructed Web page.
By using specially crafted HTML files, an attacker can easily bypass the script-filtering mechanism of eSafe Gateway, which is marketed by Aladdin Knowledge Systems.
The flaw was discovered by security firm eDvice Security Services which said users should "not rely on eSafe Gateway for HTML filtering until Aladdin fixes the problem".
Details of the problem, which is believed to affect version 3 eSafe Gateway, and possibly earlier versions, have been posted on security mailing list BugTraq and by eDvice. Aladdin Knowledge Systems has not published any advice to its users about the issue but has already come in for some flak from security experts.
Richard Stagg, senior consultant at Information Risk Management, said Aladdin was guilty of a "trivial and silly error" in allowing such a straightforward exploit to be successful.
Users of the software could be given a false sense of security, leaving them even more vulnerable to attack, he claimed. ®
