Title: CAID 34013 - CA Common Services CAIRIM on z/OS LMP SVC 
vulnerability

CA Vulnerability ID: 34013

CA Advisory Date: 2006-05-02

Discovered By: IBM Global Services


Impact: Local attacker can gain escalated privileges.


Summary: 
A potential vulnerability issue exists in our CAIRIM LMP 
solution for z/OS. CAIRIM is delivered as part of CA's z/OS Common 
Services, and the LMP component provides licensing services to 
many of CA's z/OS solutions. IBM Global Services discovered an 
integrity problem, which could be exploited by an expert user of a 
z/OS system that utilizes CA's CAIRIM LMP component. We worked 
with IBM Global Services to understand the nature of the problem 
and to make certain that the remedy we have now provided addresses 
the problem completely.

CA has confirmed the presence of this vulnerability and has 
developed a corrective update that provides comprehensive 
protection for our customers. Additional Quality Assurance testing 
has been completed and an official published solution has been 
made available as of 2006-05-02.

The vulnerability is an integrity exposure associated with the way 
the CAIRIM LMP SVC operates in conjunction with the legitimate SVC 
invoking code. An attacker can potentially utilize a problem state 
program to take advantage of this integrity exposure and obtain 
supervisor state, key 0. Once the attacker achieves supervisor 
state, key 0, he could possibly then update any system memory 
areas he chooses. An attacker can use a carefully crafted program 
in supervisor state to potentially compromise system security 
settings and gain unauthorized access to other system related 
resources. Although recently discovered, this exposure has been 
present in the CAIRIM LMP code since its inception.


Mitigating Factors: Attacker must have (access to) an account on 
the system.  Also, target system must be running CAIRIM LMP on a 
z/OS platform.


Severity: CA has given this vulnerability a Medium risk rating.


Affected Technologies: The LMP subcomponent of the CAIRIM v1.0
component in CA Common Services.

for this vulnerability, the following CAIRIM PTF maintenance must 
already be applied:

Determining if you are affected:

You can verify the existence of CAIRIM LMP on your system by using 
the IPCS Findmod (FMOD) command to examine storage in your z/OS 
LPA:

   1. Access IPCS from within TSO/ISPF
   2. Issue the following IPCS commands:
      SETDEF ACTIVE
      FMOD CAIRIMC

If a valid address for CAIRIMC is displayed, then CAIRIM LMP has 
been installed on the system. If CAIRIMC is present the display 
will be comparable to:

   BLS18462I Symbol X'C3C4C5C9 C7C3F0F0 F2F4C040 40404040

   40404040 40404040 40404040 404040' is not valid - no

   definition stored

   BLS18016I AMODE(31) entry point CAIRIMC is at 0D5EB000



   CAIRIMC

   LIST 0D5EB000. ASID(X'0001') LENGTH(X'21A0') MODULE(Cairimc)

Note the 0D5EB000 address is given for CAIRIMC meaning that 
CAIRIM LMP is installed.

If CAIRIM LMP is not installed, the FMOD CAIRIMC display will be 
similar to this:

   BLS18462I Symbol X'C3C4C5C9 C7C3F0F0 F2F4C040 40404040

   40404040 40404040 40404040 404040' is not valid - no

   definition stored

   BLS18462I Symbol X'C3C4C5C9 C7C3F0F0 F2F3C040 40404040

   40404040 40404040

            40404040 404040' is not valid - no definition stored

   BLS18104I Symbol LPDECAIRIMC not found
          
   BLS18015I Entry point CAIRIMC not found

In this case note the "not found" clause.
