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.

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.
