CVE-2011-0755 : Integer overflow in the mt _rand function in PHP before 5.3.4 might make it easier for context-dependent attackers to predict the return values by leveraging a script’s use of a large max parameter, as demonstrated by a value that exceeds mt_getrandmax.
The module uses ctypes to access the function from within python. In addition, the module also includes a pure python implementation of the mt _rand function as used by PHP. The mediawiki exploit is a nice showcase on how to use both of these classes (check exploits /mediawiki.py).
PHP’s rand() generator is a based on the system implementation, which is usually a weak LCG or LFSR (see Andrey’s comment below). For more info on why these types of generators are bad, take a look at How insecure are non-cryptographic random number generators?. The mt _rand() function uses Mersenne Twister, which isn’t much better.You can determine the internal state and all future values …
With mt _rand() an attacker would need to reset 700 passwords to get enough information to piece together the random state, but that’s assuming each call is consecutive.. other people making use of the site would make trigger mt _rand calls that the attacker is not aware of. … Can an attacker exploit microtime fed into mt _rand? Possibly …
Exactly. The primary reason mt _rand() is considered better than just rand() is that the underlying libc RNG that rand() uses is an unknown quantity the implementation is not part of the C specification. The RNG used by one implementation might be totally different to the RNG used in another implementation. Conversely, we know exactly what mt _rand() is doing and it will be doing that on every …

Collection of Metasploit modules, The Exploit Database is a repository for exploits and proof-of-concepts rather than advisories, making it a valuable resource for those who need actionable data right away. The Google Hacking Database (GHDB) is a categorized index of Internet search engine queries designed to uncover interesting, and usually sensitive, information made publicly …
Banyak yang mengira ini pasti sejenis SQL injection atau exploit pada database Oracle. Sebenarnya padding oracle attack tidak ada hubungannya sama sekali dengan database oracle, ini adalah jenis serangan yang meng-interogasi ‘the oracle’ kemudian dengan matematika sederhana (operasi XOR) menggunakan jawaban ‘the oracle’ untuk mendekrip …
