CVE-2026-40118MEDIUM	Generated title:Arcserve UDP Console Incorrectly Specified Destination in Communication Channel UDP Console provided by Arcserve contains an incorrectly specified destination in a communication channel vulnerability. When a user configures an activation server hostname of the affected product to a dummy URL, the product may unintentionally communicate with the dummy domain, causing information disclosure. CWE-941Apr 16, 2026	CVSS5.1v4.0	EPSS0.178%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
CVE-2025-34520HIGH	Arcserve UDP < 10.2 Authentication Bypass An authentication bypass vulnerability in Arcserve Unified Data Protection (UDP) allows unauthenticated attackers to gain unauthorized access to protected functionality or user accounts. By manipulating specific request parameters or exploiting a logic flaw, an attacker can bypass login mechanisms without valid credentials and access administrator-level features. This vulnerability affects all UDP versions prior to 10.2. UDP 10.2 includes the necessary patches and requires no action. Versions 8.… CWE-288Aug 27, 2025	CVSS7.7v4.0	EPSS0.369%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
CVE-2025-34521MEDIUM	Arcserve UDP < 10.2 Reflected Cross-Site Scripting (XSS) A reflected cross-site scripting (XSS) vulnerability exists in the web interface of the Arcserve Unified Data Protection (UDP), where unsanitized user input is improperly reflected in HTTP responses. This flaw allows remote attackers with low privileges to craft malicious links that, when visited by another user, execute arbitrary JavaScript in the victim’s browser. Successful exploitation may lead to session hijacking, credential theft, or other client-side impacts. The vulnerability requires u… CWE-79Aug 27, 2025	CVSS4.8v4.0	EPSS0.212%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
CVE-2025-34522CRITICAL	Arcserve UDP < 10.2 Pre-Authentication Heap Overflow A heap-based buffer overflow vulnerability exists in the input parsing logic of Arcserve Unified Data Protection (UDP). This flaw can be triggered without authentication by sending specially crafted input to the target system. Improper bounds checking allows an attacker to overwrite heap memory, potentially leading to application crashes or remote code execution. Exploitation occurs in the context of the affected process and does not require user interaction. The vulnerability poses a high risk … CWE-122Aug 27, 2025	CVSS9.2v4.0	EPSS0.556%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
CVE-2025-34523CRITICAL	Arcserve UDP < 10.2 Pre-Authentication Heap Overflow A heap-based buffer overflow vulnerability exists in the network-facing input handling routines of Arcserve Unified Data Protection (UDP). This flaw is reachable without authentication and results from improper bounds checking when processing attacker-controlled input. By sending specially crafted data, a remote attacker can corrupt heap memory, potentially causing a denial of service or enabling arbitrary code execution depending on the memory layout and exploitation techniques used. This vulne… CWE-122Aug 27, 2025	CVSS9.2v4.0	EPSS0.53%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
CVE-2024-0801HIGH	Unauthenticated DoS in Arcserve Unified Data Protection A denial of service vulnerability exists in Arcserve Unified Data Protection 9.2 and 8.1 in ASNative.dll.

CVE-2024-0800HIGH	Authentication Bypass via wizardLogin in Arcserve Unified Data Protection A path traversal vulnerability exists in Arcserve Unified Data Protection 9.2 and 8.1 in edge-app-base-webui.jar!com.ca.arcserve.edge.app.base.ui.server.servlet.ImportNodeServlet. CWE-434Mar 13, 2024	CVSS8.8v3.1	EPSS1.03%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
CVE-2024-0799CRITICAL	Authentication Bypass via wizardLogin in Arcserve Unified Data Protection An authentication bypass vulnerability exists in Arcserve Unified Data Protection 9.2 and 8.1 in the edge-app-base-webui.jar!com.ca.arcserve.edge.app.base.ui.server.EdgeLoginServiceImpl.doLogin() function within wizardLogin. CWE-287Mar 13, 20241 related artifact	CVSS9.8v3.1	EPSS4.34%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware use1 Nuclei template	STIX
CVE-2023-42000CRITICAL	Arcserve UDP Agent Unauthenticated Path Traversal File Upload Arcserve UDP prior to 9.2 contains a path traversal vulnerability in com.ca.arcflash.ui.server.servlet.FileHandlingServlet.doUpload(). An unauthenticated remote attacker can exploit it to upload arbitrary files to any location on the file system where the UDP agent is installed. CWE-22Nov 27, 2023	CVSS9.8v3.1	EPSS1.47%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
CVE-2023-41999CRITICAL	Arcserve UDP Management Authentication Bypass An authentication bypass exists in Arcserve UDP prior to version 9.2. An unauthenticated, remote attacker can obtain a valid authentication identifier that allows them to authenticate to the management console and perform tasks that require authentication. CWE-287Nov 27, 2023	CVSS9.8v3.1	EPSS1.44%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
CVE-2023-41998CRITICAL	Arcserve UDP Unauthenticated RCE Arcserve UDP prior to 9.2 contained a vulnerability in the com.ca.arcflash.rps.webservice.RPSService4CPMImpl interface. A routine exists that allows an attacker to upload and execute arbitrary files.

CVE-2020-27858HIGH	This vulnerability allows remote attackers to disclose sensitive information on affected installations of CA Arcserve D2D 16.5. Authentication is not required to exploit this vulnerability. The specific flaw exists within the getNews method. Due to the improper restriction of XML External Entity (XXE) references, a specially-crafted document specifying a URI causes the XML parser to access the URI and embed the contents back into the XML document for further processing. An attacker can leverage … CWE-611Jan 20, 2021	CVSS7.5v3.1	EPSS73.8%	PoCs0	SignalsNot listed in CISA KEVNo known ransomware useNo Nuclei templates	STIX
