| CVE-2021-44228 | JNDI Injection Remote Code Execution in Apache Log4j2 (Log4Shell) Apache Log4j2, an extremely widely used Java logging library, fails to protect its JNDI lookup feature against attacker-controlled JNDI-related endpoints (CWE-20, CWE-502), so crafted text processed by the logger causes the Java runtime to fetch and load attacker-supplied objects, leading to remote code execution. The flaw is triggered whenever attacker-controlled input reaches the logging API and is parsed for JNDI lookups, a pattern common in web servers and enterprise Java applications that log user-supplied fields such as headers or form values. Successful exploitation yields arbitrary code execution under the privileges of the affected application, giving attackers a foothold for lateral movement, data theft, and ransomware deployment. Any Java application or product that ships or bundles an affected Apache Log4j2 release is exposed, making this one of the most broadly deployed vulnerabilities ever disclosed. Exploitation is confirmed in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2021-12-10 with known ransomware use, and EPSS assigns a 100% probability of exploitation within 30 days. Do: Inventory all Java applications and dependencies for Apache Log4j2 and apply the vendor's patched updates, or remove affected assets from the network, as required by CISA's KEV catalog. Where updates are not yet available, use the temporary mitigations in CISA's ED-22-02 recommended-mitigation guidance, such as disabling message lookups, only until patches are applied. Prioritize internet-facing and business-critical systems and hunt for exploitation activity given known ransomware use. | 10.0 | 100% | KEV ransomware PoC ×9 |

Cybersecurity researchers have developed a proof-of-concept (PoC) code that exploits a recently disclosed critical flaw in the Apache OfBiz open-source Enterprise Resource Planning (ERP) system to execute a memory-resident payload.
The vulnerability in question is CVE-2023-51467 (CVSS score: 9.8), a bypass for another severe shortcoming in the same software (CVE-2023-49070, CVSS score: 9.8) that could be weaponized to circumvent authentication and remotely execute arbitrary code.
While it was fixed in Apache OFbiz version 18.12.11 released last month, threat actors have been observed attempting to exploit the flaw, targeting vulnerable instances.
The latest findings from VulnCheck show that CVE-2023-51467 can be exploited to execute a payload directly from memory, leaving little to no traces of malicious activity.
Security flaws disclosed in Apache OFBiz (e.g., CVE-2020-9496) have been exploited by threat actors in the past, including by threat actors associated with the Sysrv botnet. Another three-year-old bug in the software (CVE-2021-29200) has witnessed exploitation attempts from 29 unique IP addresses over the past 30 days, per data from GreyNoise.
What’s more, Apache OFBiz was also one of the first products to have a public exploit for Log4Shell (CVE-2021-44228), illustrating that it continues to be of interest to both defenders and attackers alike.
CVE-2023-51467 is no exception, with details about a remote code execution endpoint (“/webtools/control/ProgramExport”) as well as PoC for command execution emerging merely days after public disclosure.
While security guardrails (i.e., Groovy sandbox) have been erected such that they block any attempts to upload arbitrary web shells or run Java code via the endpoint, the incomplete nature of the sandbox means that an attacker could run curl commands and obtain a bash reverse shell on Linux systems.
“For an advanced attacker, though, these payloads aren’t ideal,” VulnCheck’s Chief Technology Officer Jacob Baines said. “They touch the disk and rely on Linux-specific behavior.”
The Go-based exploit devised by VulnCheck is a cross-platform solution that works on both Windows and Linux as well as gets around the denylist by taking advantage of groovy.util.Eval functions to launch an in-memory Nashorn reverse shell as the payload.
“OFBiz is not widely popular, but it has been exploited in the past. There is a fair deal of hype around CVE-2023-51467 but no public weaponized payload, which called into question if it was even possible,” Baines said. “We’ve concluded that not only is it possible, but we can achieve arbitrary in memory code execution.”
