Experts from 0patch, a community of experts that aims at addressing software flaws, released an unofficial patch for the Microsoft JET Database Engine zero-day vulnerability that Trend Micro’s Zero Day Initiative (ZDI) disclosed last week.
The Microsoft JET Database Engine flaw is an out-of-bounds (OOB) write in the JET Database Engine that could be exploited by a remote attacker to execute arbitrary code on the vulnerable systems.
The zero-day vulnerability has received CVSS score of 6.8 and resides in the management of indexes in JET. An attacker can use specially crafted data in a database file to trigger a write past the end of an allocated buffer.
According to the ZDI’s disclosure policy, details on the vulnerability could be released 120 days after the vendor was notified on the issue, even if the flaw was still unpatched.
ZDI also published the proof-of-concept (PoC) exploit code for the vulnerability.
The 0patch community is known to develop tiny patches, usually less than 30 bytes in size, it released a fix within 24 hours after the public disclosure of the issue.
0patch experts were able to devise a security patch for the zero-day in less than 24 hours.
