CWE-207: Information Exposure Through an External Behavioral Inconsistency
Information Exposure Through an External Behavioral Inconsistency
Weakness ID: 207 (Weakness Variant)
Status: Draft
Description
Description Summary
The product behaves differently than other products like it, in a way that is observable to an attacker and exposes security-relevant information about which product is being used.
Honeypot generates an error with a "pwd" command
in a particular directory, allowing attacker to know they are in a honeypot
system.
Potential Mitigations
Compartmentalize your system to have "safe" areas where trust
boundaries can be unambiguously drawn. Do not allow sensitive data to go
outside of the trust boundary and always be careful when interfacing
with a compartment outside of the safe area.
Setup generic response pages for error condition. The error page
should not disclose information about the success or failure of a
sensitive operation. For instance, the login page should not confirm
that the login is correct and the password incorrect. The attacker who
tries random account name may be able to guess some of them. Confirming
that the account exists would make the login page more susceptible to
brute force attack.
