72% of organizations remain vulnerable to the Log4Shell vulnerability as of October 1, 2022, Tenable's latest telemetry study has revealed, based on data collected from over 500 million tests. "While an organization may have been fully remediated at some point, as they've added new assets to their environments, they are likely to encounter Log4Shell again and again. Eradicating Log4Shell is an ongoing battle that calls for organizations to continually assess their environments for the flaw, as well as other known vulnerabilities."

Apache Commons Text flaw is not a repeat of Log4Shell (CVE-2022-42889)
2022-10-19 13:09

A freshly fixed vulnerability in the Apache Commons Text library has been getting attention from security researchers these last few days, worrying it could lead to a repeat of the Log4Shell dumpster fire. The final verdict shows there's no need to panic: while the vulnerability is exploitable, "The nature of the vulnerability means that unlike Log4Shell, it will be rare that an application uses the vulnerable component of Commons Text to process untrusted, potentially malicious input," says Rapid7 AI researcher Erick Galinkin.
