Actual exam question for Eccouncil's 212-89 exam

Question #: 89
Topic #: 9

[Introduction to Incident Handling and Response]

If the browser does not expire the session when the user fails to logout properly, which of the following OWASP Top 10 web vulnerabilities is caused?

AA7: Cross-site scripting

BA3: Sensitive- data exposure

CA2: Broken authentication

DA5: Broken access control

Show Suggested Answer

Suggested Answer: C

When a browser does not expire a session after the user fails to logout properly, it is indicative of a vulnerability related to broken authentication. Broken authentication is a security issue where attackers can exploit flaws in the authentication mechanism to impersonate other users or take over their sessions. Failure to properly manage session lifetimes, such as not expiring sessions on logout, can allow an attacker to reuse old sessions or session IDs, potentially gaining unauthorized access to user accounts. This vulnerability is classified under A2: Broken Authentication in the OWASP Top 10, which lists the most critical web application security risks. The OWASP Top 10 serves as a guideline for developers and web application providers to understand and mitigate common security risks.

Wait, are we sure it's not D) A5? Seems like a close call.

Haha, this is a classic "which vulnerability is it" question. I'm going with C, gotta keep those sessions secure!

Hmm, I'd say B) A3: Sensitive data exposure. That open session could reveal all kinds of sensitive info.

I'm going with D) A5: Broken access control. Sounds like a session management issue to me.

Definitely C. Leaving the session open is a security nightmare waiting to happen.

C) A2: Broken authentication is the correct answer. If the browser doesn't expire the session, it can lead to unauthorized access.

I’m confused; I thought session management could also tie into access control issues, but I guess that’s more about A5?

I practiced a question similar to this, and I feel like it was about authentication problems, so I'm leaning towards A2 as well.

I'm not entirely sure, but I remember something about session expiration being linked to sensitive data exposure. Could it be A3?

I think this might relate to A2: Broken authentication since it deals with session management issues.

Ah, I see now. If the session isn't properly expired, that means an attacker could potentially hijack the session and gain unauthorized access. That sounds like a broken authentication issue to me. I'll go with C.

I think the key here is understanding how session management is related to the OWASP Top 10. If the session isn't properly expired, that could lead to broken access control. I'm going with D.
