Hackers are trying to steal admin passwords from F5 BIG-IP devices

Programmers have begun propelling assaults against F5 BIG-IP organizing gadgets, ZDNet has learned.

Assaults have been spotted today by Rich Warren, a security analyst for the NCC Group.

In a meeting prior today, Warren disclosed to ZDNet the assaults are vindictive in nature, and programmers are endeavoring to take head passwords from the hacked gadgets.

Synopsis: BIG-IP AND CVE-2020-5902

These assaults are focusing on BIG-IP, a multi-reason organizing gadget produced by F5 Networks. Huge IP gadgets can be designed to fill in as traffic molding frameworks, load balancers, firewalls, get to entryways, rate limiters, or SSL middleware.

These gadgets are the absolute most well known systems administration items being used today, and they are utilized to support probably the biggest and delicate systems around.

Enormous IP gadgets are utilized in government systems, on the systems of web access suppliers, inside distributed computing server farms, and they’re generally sent across big business systems.

The gadgets are so incredible and well known that on its site, F5 claims that 48 of the 50 organizations remembered for the Fortune 50 rundown depend on BIG-IP frameworks.

On Wednesday, F5 Networks distributed fixes and discharged a security warning about a “remote code execution” defenselessness in BIG-IP gadgets.

F5 said the helplessness, followed as CVE-2020-5902, could permit aggressors to assume full responsibility for unpatched frameworks that are available on the web.

The weakness was regarded so perilous that it got a 10 seriousness score, the greatest on the CVSSv3 seriousness scale. This score implies the weakness is anything but difficult to misuse, computerize, can be utilized over the web, and doesn’t require substantial accreditations or propelled coding abilities to exploit.S

The digital security network expected that this bug would go under dynamic assaults when programmers made sense of how they could misuse it.

Digital security specialists have been attempting to raise the alert about the critical need to fix this bug, immediately, since Wednesday, when it got open, as any fruitful assaults would allow danger on-screen characters full access to a portion of the world’s most significant IT systems.

Their endeavors to raise regard for this issue were helped by US Cyber Command, which, on Friday night, only hours before July fourth, requested that framework managers set aside the effort to fix BIG-IP gadgets, likewise dreading something very similar.

As indicated by Warren, those assaults started only hours after the US Cyber Command tweet. Warren, who is as of now working BIG-IP honeypots – servers made to look like BIG-IP gadgets – said he distinguished pernicious assaults originating from five diverse IP addresses.

In logs imparted to ZDNet, Warren called attention to the wellspring of those assaults and affirmed they were noxious.

“The powerlessness permits you to summon .JSP documents utilizing a traversal succession,” Warren revealed to ZDNet before today.

“This, thusly, permits you to (ab)use usefulness of in any case validated .JSP documents to do things like read records or, in the long run, execute code.

“Up until this point, what we’ve seen is an aggressor perusing different various records from the honeypots and executing orders by means of an inherent .JSP document. With this they had the option to dump out the encoded administrator passwords, settings., and so forth.,” Warren said.


The BIG-IP weakness is the kind of securit ybug that country state hacking gatherings and ransomware packs have been misusing for close to 12 months – however in different items.

Since August, hacking bunches have been misusing comparative RCE bugs in Pulse Secure VPNs and Citrix organizing doors to increase a toehold on corporate systems, and afterward plant secondary passages, take touchy documents, or introduce ransomware.

The Pulse Secure and Citrix bugs have been the bread and butter for ransomware posses, specifically. As a rule, they didn’t abuse the bugs immediately. They planted secondary passages, and afterward returned days, weeks, or months after the fact to adapt their entrance.

Ransomware posses like REvil, Maze, or Netwalker have been known to intensely depend on these kinds of bugs to assault a portion of the world’s biggest organizations, and security specialists state the BIG-IP defenselessness is only the sort of bug that will fuel their next flood of assaults
