Critical Adobe ColdFusion Flaw Added to CISA's Exploited Vulnerability Catalog

Image
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical security flaw in Adobe ColdFusion to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active exploitation. The vulnerability, cataloged as  CVE-2023-26359  (CVSS score: 9.8), relates to a deserialization flaw present in Adobe ColdFusion 2018 (Update 15 and earlier) and ColdFusion 2021 (Update 5 and earlier) that could result in arbitrary code execution in the context of the current user without requiring any interaction. Deserialization (aka unmarshaling) refers to the process of reconstructing a data structure or an object from a byte stream. But when it's performed without validating its source or sanitizing its contents, it can lead to unexpected consequences such as code execution or denial-of-service (DoS). It was patched by Adobe as part of updates issued in March 2023. As of writing, it's immediately not clear how the flaw is being abused in the wild. That said,

CISA Adds Citrix ShareFile Flaw to KEV Catalog Due to In-the-Wild Attacks

  The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a critical security flaw in Citrix ShareFile storage zones controller to its Known Exploited Vulnerabilities ( KEV ) catalog, based on evidence of active in-the-wild exploitation. Tracked as  CVE-2023-24489  (CVSS score: 9.8), the shortcoming has been described as an improper access control bug that, if successfully exploited, could allow an unauthenticated attacker to compromise vulnerable instances remotely. The problem is rooted in ShareFile's handling of cryptographic operations, enabling adversaries to upload arbitrary files, resulting in remote code execution. "This vulnerability affects all currently supported versions of customer-managed ShareFile storage zones controller before version 5.11.24," Citrix said in an advisory released in June. Dylan Pindur of Assetnote has been credited with discovering and reporting the issue. It's worth noting that the first signs of exploitation of th
