Vulnerability Summary
Multiple vulnerabilities in QRadar allow a remote unauthenticated attackers to cause the product to execute arbitrary commands. Each vulnerability on its own is not as strong as their chaining – which allows a user to change from unauthenticated to authenticated access, to running commands, and finally running these commands with root privileges.

Vendor Response
“You reported this vulnerability to IBM on January 25th, and we notified you on April 27th that the vulnerability had been fixed. Here is the link to our public notice and the independent researcher that reported it to you was acknowledged: http://www.ibm.com/support/docview.wss?uid=swg22015797. We thank you for your efforts in reporting these issues to us, and for delaying your disclosures until IBM published a fix.

For your awareness the third vulnerability you reported with regards to privilege escalation to root had been fixed in patches a few weeks prior to the initial report. This is the bulletin for that particular CVE: http://www.ibm.com/support/docview.wss?uid=swg22012293.

After concerns regarding the scoring of the other vulnerabilities were brought to our attention, the scoring has been reviewed and some corrections made. The reported issue has been separated into separate CVEs: a new one for the authentication bypass CVE-2018-1612; and the existing one for the command injection as an unprivileged user CVE-2018-1418. The updated descriptions and scoring for these CVEs is as follows:

CVE-2018-1612 IBM QRadar Incident Forensics could allow a remote attacker to bypass authentication and obtain sensitive information
CVSS Base: 5.8
CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N

CVE-2018-1418 IBM QRadar Incident Forensics could allow an authenticated attacker to execute commands as ‘nobody’.
CVSS Base: 7.4
CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:L

The issue in the initial scoring occurred due to a miscommunication in our process and we are working to improve our process going forward. We apologize for the problematic scoring in our initial disclosure. Also while the fix for the authentication CVE-2018-1612 was included in 7.2.8 Patch 11 we discovered an issue with 7.3.1 Patch 2 and are issuing an iFix as outlined here www.ibm.com/support/docview.wss?uid=swg22017062. The command injection issue is fixed in 7.3.1 Patch 2 as previously published.”

Vulnerability Summary
A use after free vulnerability in AF_LLC allows local attackers to control the flow of code that the kernel executes, allowing them to cause it to run arbitrary code and gain elevated privileges.

Vendor Response
The vulnerability was reported to the Kernel Security, which asked us to contact the netdev team. A patch was provided by the netdev team, on the 27th of March, and was later integrated into the main code of Linux (we are not certain when).

See our full scope at: https://blogs.securiteam.com/index.php/product_scope

Vulnerability Summary
Multiple vulnerabilities in TrustPort’s management product allow remote unauthenticated attackers to cause the product to execute arbitrary code.

TrustPort Management “offers you an effective and practical way to install centrally, configure and update antivirus software in your network and it enables mass administration of TrustPort products. Central administration from TrustPort brings you simple application of corporate security policies, monitoring of security incidents or the remote starting of tasks”.

Vendor Response
The vulnerability was reported to the vendor on March 6th, the following response was received on the 6th of March:
“thanks for information. We are going to correct the errors in following version of the SW.”

No further response was received, though 3 more emails were sent by us to the company between the March 6th and the date of publication. We have no idea of how to resolve this bug, the only workaround is to not expose the administrative port to untrusted networks.
