CWE-122 - Heap-based Buffer Overflow

Summary

A heap-based buffer overflow vulnerability exists in the 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 vulnerability is similar in nature to CVE-2025-34522 but affects a separate code path or component. No user interaction is required, and exploitation occurs in the context of the vulnerable process. This vulnerability affects all UDP versions prior to 10.2. UDP 10.2 includes the necessary patches and requires no action. Versions 8.0 through 10.1 are supported and require either patch application or upgrade to 10.2. Versions 7.x and earlier are unsupported or out of maintenance and must be upgraded to 10.2 to remediate the issue.

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 vulnerability is similar in nature to CVE-2025-34522 but affects a separate code path or component. No user interaction is required, and exploitation occurs in the context of the vulnerable process. This vulnerability affects all UDP versions prior to 10.2. UDP 10.2 includes the necessary patches and requires no action. Versions 8.0 through 10.1 are supported and require either patch application or upgrade to 10.2. Versions 7.x and earlier are unsupported or out of maintenance and must be upgraded to 10.2 to remediate the issue."

Feiten

Arcserve heeft kwetsbaarheden verholpen in Arcserve Unified Data Protection (UDP) voor alle versies vóór 10.2.

Interpretaties

De kwetsbaarheden omvatten een authenticatie-bypass die ongeauthenticeerde kwaadwillenden toegang geeft tot beschermde functies, een reflected cross-site scripting (XSS) kwetsbaarheid die het mogelijk maakt voor kwaadwillenden om willekeurige JavaScript-code uit te voeren in de browsers van gebruikers, en heap-based buffer overflow kwetsbaarheden die ernstige gevolgen kunnen hebben, zoals applicatiecrashes en remote code-executie.

Oplossingen

Arcserve heeft updates uitgebracht om de kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
