Solution 261849 : A Security Vulnerability in the Solaris iSCSI Management Commands (iscsiadm(1M) and iscsitadm(1M)) may Allow Privilege Escalation
Bug ID
6801126
ProductSolaris 10 Operating System OpenSolaris
Date of Resolved Release21-Sep-2009
SA Document BodyA security vulnerability in the Solaris iSCSI Management commands (iscsiadm(1M) and iscsitadm(1M)) may allow privilege escalation:
1. Impact
A security vulnerability in the Solaris iSCSI management commands (iscsiadm(1M) and iscsitadm(1M)) may allow a local user who has been assigned an RBAC execution profile which specifies additional privileges for the iscsiadm(1M) or iscsitadm(1M) commands, such as the "File System Management" profile, to execute arbitrary commands with the privileges specified in the RBAC profile.
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
- Solaris 10 with patch 119090-16 through 119090-32 and without patch 119090-33
- OpenSolaris based upon builds snv_28 through snv_109
- Solaris 10 with patch 119091-16 through 119091-33 and without patch 119091-34
- OpenSolaris based upon builds snv_28 through snv_109
Note 2: OpenSolaris distributions may include additional bug fixes above and beyond the build from which it was derived. To determine the base build of OpenSolaris, the following command can be used:
$ uname -v
snv_86
The assignment of profiles to users is configured in the user_attr(4) database. The exec_attr(4) database specifies the execution attributes associated with profiles. Thus, if a system is configured to only reference local files for the user_attr(4) and exec_attr(4) databases then users who have been assigned a profile containing iscsiadm(1M) or iscsitadm(1M) can be determined as follows:
$ egrep 'iscsiadm|iscsitadm' /etc/security/exec_attr
File System Management:solaris:cmd:::/usr/sbin/iscsiadm:euid=0;privs=basic
File System Management:solaris:cmd:::/usr/sbin/iscsitadm:euid=0;privs=basic
$ grep 'File System Management' /etc/user_attr
username::::profiles=File System Management
3. Symptoms
There are no predictable symptoms that would indicate the described issue has occurred.
4. Workaround
To work around this issue until patches can be applied, remove references to the iscsiadm(1M) and iscsitadm(1M) commands from the exec_attr(4) database. This will result in users who have been assigned the relevant execution profile(s) to no longer be granted privileged access to the iscsiadm(1M) and iscsitadm(1M) commands.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
- Solaris 10 with patch 119090-33 or later
- OpenSolaris based upon builds snv_110 or later
- Solaris 10 with patch 119091-34 or later
- OpenSolaris based upon builds snv_110 or later
