A bug on Ford Motor Firm’s web site allowed for accessing delicate programs and acquiring proprietary information, similar to buyer databases, worker information, inner tickets, and so on.
The information publicity stemmed from a misconfigured occasion of Pega Infinity buyer engagement system operating on Ford’s servers.
From information exfiltration to account takeovers
This week, researchers have disclosed a vulnerability discovered on Ford’s web site that allow them peek into confidential firm information, databases and carry out account takeovers.
The vulnerability was found by Robert Willis and break3r, with additional validation and assist supplied by members of Sakura Samurai moral hacking group—Aubrey Cottle, Jackson Henry, and John Jackson.
The situation is attributable to CVE-2021-27653, an data publicity vulnerability in improperly configured Pega Infinity buyer administration system cases.
Researchers shared many screenshots of Ford’s inner programs and databases with BleepingComputer. For instance, the corporate’s ticketing system is proven beneath:
To take advantage of the difficulty, an attacker would first should entry the backend internet panel of a misconfigured Pega Chat Entry Group portal occasion:
As seen by BleepingComputer, completely different payloads supplied as URL arguments may allow attackers to run queries, retrieve database tables, OAuth entry tokens, and carry out administrative actions.
The researchers state that a few of the uncovered property contained delicate Private Identifiable Info (PII), and included:
- Buyer and worker information
- Finance account numbers
- Database names and tables
- OAuth entry tokens
- Inner assist tickets
- Person profiles throughout the group
- Pulse actions
- Inner interfaces
- Search bar historical past
“The influence was massive in scale. Attackers may use the vulnerabilities recognized within the damaged entry management and acquire troves of delicate information, carry out account takeovers, and acquire a considerable quantity of information,” Willis writes in a blog posting.
Took six months to ‘power disclose’
In February 2021, the researchers had reported their findings to Pega, who fastened the CVE of their chat portal comparatively rapidly.
The difficulty was additionally reported to Ford across the identical time by way of their HackerOne vulnerability disclosure program.
However, the researchers instructed BleepingComputer that communication from Ford was skinny and light because the accountable disclosure timeline progressed:
“At one time limit, they fully stopped answering our questions. It took HackerOne mediation to get an preliminary response on our vulnerability submission from Ford,” John Jackson instructed BleepingComputer in an e mail interview.
Jackson states that because the disclosure timeline progressed additional, the researchers heard again from HackerOne solely after tweeting concerning the flaw, however with out giving out any delicate particulars:
Listed here are a few of the many issues which might be uncovered:
Buyer Databases, Worker Information, Inner Ticketing Methods, OAuth Tokens, Request Data, Funds…really there are about 8 pages value of Database Tables so it might be actually troublesome to specific.

“When the vulnerability was marked as resolved, Ford ignored our disclosure request. Subsequently, HackerOne mediation ignored our request for assist disclosing which will be seen within the PDF.”
“We needed to wait the total six months to power disclose per HackerOne’s policy out of concern of the regulation and unfavourable repercussions,” continued Jackson.
Right now, Ford’s vulnerability disclosure program does not offer financial incentives or bug bounties, so a coordinated disclosure in mild of public curiosity was the one “reward” researchers had been hoping for.
A copy of the disclosure report shared with BleepingComputer signifies Ford kept away from commenting on particular security-related actions.
“The findings you submitted… are thought of personal. These vulnerability experiences are supposed to stop compromises which can require disclosure.”
“On this state of affairs, the system was taken offline shortly after you submitted your findings to HackerOne,” Ford shared with HackerOne and the researchers, as per the dialogue in the PDF.
Though the endpoints had been taken offline by Ford inside 24 hours of the report, the researchers remark in the identical report that the endpoints remained accessible even afterward, and requested one other evaluation and remediation.
It isn’t but recognized if any menace actors exploited the vulnerability to breach programs at Ford, or if delicate buyer/worker PII was accessed.
BleepingComputer reached out to Ford a number of occasions effectively prematurely of publishing however we didn’t hear again.
