PoC vom 12.12.2018 um 06:19 Uhr | Quelle packetstormsecurity.comWhen the WordPress plugin Snap Creek Duplicator restores a backup, it leaves dangerous files in the filesystem such as installer.php and installer-backup.php. These files allow anyone to call a function that overwrite the wp-config.php file AND this function does not sanitize POST parameters before inserting them inside the wp-config.php file, leading to arbitrary PHP code execution. WARNING: This exploit WILL break the wp-config.php file. If possible try to restore backups of the configuration after the exploit to make the WordPress site work again.
Dynamic Loader Oriented Programming - Wiederganger Proof Of Concept
PoC vom 12.12.2018 um 02:16 Uhr | Quelle packetstormsecurity.comThis paper and proof of concept describes the Wiederganger-Attack, a new attack vector that reliably allows to escalate unbounded array access vulnerabilities occurring in specifically allocated memory regions to full code execution on programs running on i386/x86_64 Linux. Wiederganger-attacks abuse determinism in Linux ASLR implementation combined with the fact that (even with protection mechanisms such as relro and glibc's pointer mangling enabled) there exist easy-to-hijack, writable (function) pointers in application memory.
