This is a gathering of various issues that may happen amid broken verification, however they don't all originate from a similar underlying driver.
Expecting that regardless anybody needs to roll their own verification code in 2015 (what are you thinking??), I exhort against it. It is to a great degree difficult to get right, and there are a heap of conceivable traps, just to specify a couple:
- The URL may contain the session id and break it in the referer header to another person.
- The passwords won't not be encoded either away or travel.
- The session ids may be unsurprising, consequently getting entrance is trifling.
- Session obsession may be conceivable.
- Session seizing may be conceivable, timeouts not actualized right or utilizing HTTP (no SSL), and so forth…
Counteractive action: The most direct approach to maintain a strategic distance from this web security weakness is to utilize a system. You may have the capacity to execute this accurately, however the previous is substantially less demanding. In the event that you would like to roll your own code, be to a great degree suspicious and instruct yourself on what the traps are. There are many.
