Title: CAID 34013 - CA Common Services CAIRIM on z/OS LMP SVC=20
vulnerability

CA Vulnerability ID: 34013

CA Advisory Date: 2006-05-02

Discovered By: IBM Global Services


Impact: Local attacker can gain escalated privileges.


Summary:=20
A potential vulnerability issue exists in our CAIRIM LMP=20
solution for z/OS. CAIRIM is delivered as part of CA's z/OS Common=20
Services, and the LMP component provides licensing services to=20
many of CA's z/OS solutions. IBM Global Services discovered an=20
integrity problem, which could be exploited by an expert user of a=20
z/OS system that utilizes CA's CAIRIM LMP component. We worked=20
with IBM Global Services to understand the nature of the problem=20
and to make certain that the remedy we have now provided addresses=20
the problem completely.

CA has confirmed the presence of this vulnerability and has=20
developed a corrective update that provides comprehensive=20
protection for our customers. Additional Quality Assurance testing=20
has been completed and an official published solution has been=20
made available as of 2006-05-02.

The vulnerability is an integrity exposure associated with the way=20
the CAIRIM LMP SVC operates in conjunction with the legitimate SVC=20
invoking code. An attacker can potentially utilize a problem state=20
program to take advantage of this integrity exposure and obtain=20
supervisor state, key 0. Once the attacker achieves supervisor=20
state, key 0, he could possibly then update any system memory=20
areas he chooses. An attacker can use a carefully crafted program=20
in supervisor state to potentially compromise system security=20
settings and gain unauthorized access to other system related=20
resources. Although recently discovered, this exposure has been=20
present in the CAIRIM LMP code since its inception.


Mitigating Factors: Attacker must have (access to) an account on=20
the system. Also, target system must be running CAIRIM LMP on a=20
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.=20

Determining if you are affected:

You can verify the existence of CAIRIM LMP on your system by using=20
the IPCS Findmod (FMOD) command to examine storage in your z/OS=20
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=20
been installed on the system. If CAIRIMC is present the display=20
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=20
CAIRIM LMP is installed.

If CAIRIM LMP is not installed, the FMOD CAIRIMC display will be=20
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
=20
BLS18015I Entry point CAIRIMC not found

In this case note the "not found" clause.
