The U.S. Cybersecurity and Infrastructure Safety Company (CISA) on Monday added a now-patched high-severity safety flaw impacting Acclaim Methods USAHERDS to the Identified Exploited Vulnerabilities (KEV) catalog, based mostly on proof of energetic exploitation within the wild.
The vulnerability in query is CVE-2021-44207 (CVSS rating: 8.1), a case of hard-coded, static credentials in Acclaim USAHERDS that would permit an attacker to in the end execute arbitrary code on vulnerable servers.
Particularly, it considerations using static ValidationKey and DecryptionKey values in model 7.4.0.1 and prior that might be weaponized to realize distant code execution on the server that runs the applying. That mentioned, an attacker must leverage another means to acquire the keys within the first place.
“These keys are used to offer safety for the applying ViewState,” Google-owned Mandiant mentioned in advisory for the flaw again in December 2021. “A risk actor with data of those keys can trick the applying server into deserializing maliciously crafted ViewState knowledge.”
“A risk actor with data of the validationKey and decryptionKey for an internet software can assemble a malicious ViewState that passes the MAC verify and will probably be deserialized by the server. This deserialization may end up in the execution of code on the server.”
Whereas there are not any new experiences of CVE-2021-44207 being weaponized in real-world assaults, the vulnerability was recognized as being abused by the China-linked APT41 risk actor again in 2021 as a zero-day as a part of assaults focusing on six U.S. state authorities networks.
Federal Civilian Govt Department (FCEB) companies are really useful to use vendor-provided mitigations by January 13, 2025, to safeguard their networks in opposition to energetic threats.
The event comes as Adobe warned of a important safety flaw in ColdFusion (CVE-2024-53961, CVSS rating: 7.8), which it mentioned already has a identified proof-of-concept (PoC) exploit that would trigger an arbitrary file system learn.
The vulnerability has been addressed in ColdFusion 2021 Replace 18 and ColdFusion 2023 Replace 12. Customers are suggested to use the patches as quickly as attainable to mitigate potential dangers.
