The Shadowserver Foundation has been seeing attempts to exploit a critical vulnerability affecting the Apache OFBiz open source enterprise resource planning (ERP) system.
Apache OFBiz is leveraged by several ERP and other types of projects, including the widely used Atlassian Jira issue tracking and project management software.
The nonprofit cybersecurity organization Shadowserver reported seeing signs of in-the-wild exploitation for an Apache OFBiz vulnerability tracked as CVE-2023-49070 shortly after details of a different OFBiz bug, CVE-2023-51467, were disclosed by SonicWall.
SonicWall, whose researchers discovered CVE-2023-51467 during a root cause analysis of CVE-2023-49070, disclosed technical details on December 26. The security firm explained that CVE-2023-51467 is the result of an incomplete patch for CVE-2023-49070.
Apache OFBiz developers were notified about CVE-2023-51467 and version 18.12.11 was released last week to fix the vulnerability.
The security hole can be exploited to bypass authentication and achieve server-side request forgery (SSRF), enabling the attacker to obtain sensitive information and possibly to execute arbitrary code.
Proof-of-concept (PoC) exploits have been publicly available for CVE-2023-49070 (the older flaw) and the Shadowserver Foundation on Thursday reported seeing “quite a few scans” targeting the vulnerability.
The organization said the available PoCs have been used to look for vulnerable systems, and later clarified that attackers have also attempted to execute arbitrary code on impacted hosts.
Shadowserver has urged organizations to ensure that their systems are patched against the newer vulnerability as well.
According to the internet search engine Hunter, there were 170 internet-exposed OFBiz instances in early December, but that number has now dropped to just over 70.
This is not the only critical Apache vulnerability targeted by threat actors in recent weeks. Hackers have also been scanning the internet for systems affected by CVE-2023-50164, a Struts 2 flaw that allows remote code execution.
It also came to light recently that an Apache ActiveMQ vulnerability tracked as CVE-2023-46604 had been exploited as a zero-day.
