Oracle warned its corporate customers that there is a critical-rated vulnerability in its PeopleSoft software, which is used by large companies to manage payroll and human resources, a day after a cybercrime group took credit for abusing the flaw as part of a mass-hacking campaign.
The company published the security advisory on Thursday after the hacking group ShinyHunters claimed to have breached more than 100 organizations that use PeopleSoft servers.
Mandiant, the Google-owned security unit that investigates cyberattacks, warned in a blog post that the new Oracle flaw is the same bug that the ShinyHunters group is abusing in its hacking campaign targeting PeopleSoft customers.
Oracle, which has not released a patch for the vulnerability at the time of writing, said in the advisory that the bug can be exploited over the internet without needing any authentication, such as a password.
The tech giant recommended that customers who use PeopleSoft software apply its mitigations to prevent exploitation.
