The U.S. Cybersecurity and Infrastructure Safety Company (CISA) on Monday added a now-patched high-severity safety flaw impacting Acclaim Programs USAHERDS to the Identified Exploited Vulnerabilities (KEV) catalog, based mostly on proof of lively 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 might permit an attacker to in the end execute arbitrary code on prone servers.
Particularly, it considerations the usage of 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 stated, an attacker must leverage another means to acquire the keys within the first place.
“These keys are used to supply safety for the applying ViewState,” Google-owned Mandiant stated in advisory for the flaw again in December 2021. “A risk actor with information of those keys can trick the applying server into deserializing maliciously crafted ViewState information.”
“A risk actor with information of the validationKey and decryptionKey for an online software can assemble a malicious ViewState that passes the MAC test and might be deserialized by the server. This deserialization may end up in the execution of code on the server.”
Whereas there are not any new reviews 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 concentrating on six U.S. state authorities networks.
Federal Civilian Government Department (FCEB) companies are really helpful to use vendor-provided mitigations by January 13, 2025, to safeguard their networks in opposition to lively threats.
The event comes as Adobe warned of a crucial safety flaw in ColdFusion (CVE-2024-53961, CVSS rating: 7.8), which it stated already has a identified proof-of-concept (PoC) exploit that might 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.
