Cisco has launched software program updates to deal with a vital safety flaw impacting Assembly Administration that would allow a distant, authenticated attacker to realize administrator privileges on vulnerable cases.
The vulnerability, tracked as CVE-2025-20156, carries a CVSS rating of 9.9 out 10.0. It has been described as a privilege escalation flaw within the REST API of Cisco Assembly Administration.
“This vulnerability exists as a result of correct authorization isn’t enforced upon REST API customers,” the corporate mentioned in a Wednesday advisory. “An attacker may exploit this vulnerability by sending API requests to a particular endpoint.”
“A profitable exploit may permit the attacker to realize administrator-level management over edge nodes which might be managed by Cisco Assembly Administration.”
The networking gear main credited Ben Leonard-Lagarde of Modux for reporting the safety shortcoming. It impacts the next variations of the product regardless of machine configuration –
- Cisco Assembly Administration launch model 3.9 (Patched in 3.9.1)
- Cisco Assembly Administration launch variations 3.8 and earlier (Migrate to a hard and fast release_
- Cisco Assembly Administration launch model 3.10 (Not susceptible)
Cisco has additionally launched patches to remediate a denial-of-service (DoS) flaw affecting BroadWorks that stems from improper reminiscence dealing with for sure Session Initiation Protocol (SIP) requests (CVE-2025-20165, CVSS rating: 7.5). The problem has been fastened in model RI.2024.11.
“An attacker may exploit this vulnerability by sending a excessive variety of SIP requests to an affected system,” it mentioned.
“A profitable exploit may permit the attacker to exhaust the reminiscence that was allotted to the Cisco BroadWorks Community Servers that deal with SIP visitors. If no reminiscence is accessible, the Community Servers can not course of incoming requests, leading to a DoS situation that requires handbook intervention to get better.”
A 3rd vulnerability patched by Cisco is CVE-2025-20128 (CVSS rating: 5.3), an integer underflow bug impacting the Object Linking and Embedding 2 (OLE2) decryption routine of ClamAV that would additionally end in a DoS situation.
The corporate, which acknowledged Google OSS-Fuzz for reporting the flaw, mentioned it is conscious of the existence of a proof-of-concept (PoC) exploit code, though there is no such thing as a proof it has been maliciously exploited within the wild.
CISA and FBI Element Ivanti Exploit Chains
Information of Cisco flaws comes because the U.S. authorities’s cybersecurity and legislation enforcement companies launched technical particulars of two exploit chains weaponized by nation-state hacking crews to interrupt into Ivanti’s cloud service purposes in September 2024.
The vulnerabilities in query are as follows –
The assault sequences, per the Cybersecurity and Infrastructure Safety Company (CISA) and Federal Bureau of Investigation (FBI), concerned the abuse of CVE-2024-8963 along side CVE-2024-8190 and CVE-2024-9380 in a single case, and CVE-2024-8963 and CVE-2024-9379 within the different.
It is value noting that the primary exploit chain was disclosed by Fortinet FortiGuard Labs in October 2024. In at the very least one occasion, the risk actors are believed to have carried out lateral motion after gaining an preliminary foothold.
The second exploit chain has been discovered to leverage CVE-2024-8963 together with CVE-2024-9379 to acquire entry to the goal community, adopted by unsuccessful makes an attempt to implant internet shells for persistence.
“Menace actors chained the listed vulnerabilities to realize preliminary entry, conduct distant code execution (RCE), get hold of credentials, and implant internet shells on sufferer networks,” the companies mentioned. “Credentials and delicate knowledge saved throughout the affected Ivanti home equipment must be thought of compromised.
