Is there an inherent conflict of interest in having companies decide what’s a vulnerability and what’s not? “Pls show me how to do the pwn” They decide what is considered insecure in their own products. On top of this, F5 are a CVE Numbering Authority (CNA).

“Also, uhh, this is less of a question and more of a statement”: yes, this is different from a user downloading a file from the internet and clicking on it to run it.

Why are you updating your software by extracting CAB files in 2019? There are better ways to do this.

Why not check more than just the “Signer Name” field in the certificate before extracting and processing the CAB? It’s, y’know, a certificate.Why allow CABs signed by 3 rd party certificates at all? Blocking all 3 rd party certificate would definitely make this less easy to exploit?.

If the installation required admin rights and user does not have those, he won’t be able to install the package. There is no automatic privilege escalation here either. This behavior is no different from user downloading a file from internet and clicking on it to run it in the browser.

The installation popup clearly shows the signer and the name and also displays a warning message. Respective teams have reviewed the report you have shared and it was determined that the findings is not considered a vulnerability. So I guess it’s not a bug! Don’t worry about it. Note: a URL whitelist pop up box usually shows up on a new site, but it’s really inconsistentĪnother prompt asks the user if they really want to extract the malicious CAB file, despite the fact it’s signed by “Your Employer!” rather than F5 or uRoam.Īnyway, that’s the reason F5 say it’s NOT a bug. This is (what I guess I’m calling) the “dirty” version: The user just has to click through another warning.

However, regardless, even if the “Signer Name” in the CAB signature isn’t one of those three strings, arbitrary code will still run. That’s a little tip if you fancy trying one of the more elaborate workarounds to execute arbitrary code. I will say, that “uRoam Inc” may not actually exist, since F5 bought it in 2003. It’s up to you to decide how realistic it would be to get a trusted code-signing certificate with any of those names. The f5instd.exe binary checks for those strings in the “Signer Name” field of the signature: If you want to not-exploit the not-a-bug cleanly (with only a clean, UAC popup for an F5-signed binary), the CAB file has to be signed by “F5 Networks Inc”, “F5 Networks” or “uRoam Inc”. The attacker has to have a trusted code-signing certificate to sign a malicious CAB file.The affected user has to have admin privileges, so they can click through the UAC popup.Here are the basic pre-requisites to not-exploit this not-a-bug: They say there’s too many pre-requisites for them to consider it a bug. F5 says it’s NOT a bug, so what’s the problem? I’ll talk about the “dirty” version later. To be fair, this is the “clean” version of the exploit. Then we get powershell.exe popping up, running as a subprocess of f5instd.exe, at high integrity (that’s with admin privileges).A UAC box pops up, obviously trying to run a process signed by the legitimate F5 Networks certificate.This causes the F5 Endpoint Inspector to run. That website contains a “specially-crafted” f5-epi:// URI. So they won’t be fixing it any time soon, apparently. We reported this issue to F5, who say it is “not considered a vulnerability”. There’s a few pre-requisites to get it working, and it’s a bit tougher to get it working “cleanly” (without the user having to click much). We found it can be abused to run arbitrary code, triggered by visiting a malicious website. The F5 Endpoint Inspector is an application which can be called from a web browser to scan a client for compliance. If a bug falls in the forest, and the vendor denies that it’s a bug, is it still a bug? TL DR?
