CVE-2023-53955
Published: 22 December 2025
Description
SOUND4 IMPACT/FIRST/PULSE/Eco v2.x contains an insecure direct object reference vulnerability that allows attackers to bypass authorization and access hidden system resources. Attackers can exploit the vulnerability by manipulating user-supplied input to execute privileged functionalities without proper authentication.
Mitigating Controls (NIST 800-53 r5)AI
AC-3 enforces approved authorizations for access to system resources, directly preventing IDOR exploits that bypass authorization via manipulated object references.
AC-25 implements a reference monitor to mediate all subject-object accesses according to policy, countering insecure direct object references that evade authorization checks.
SI-10 validates user-supplied inputs, blocking manipulation of object references required to exploit the IDOR vulnerability.
Security SummaryAI
CVE-2023-53955 is an insecure direct object reference vulnerability (CWE-639) present in SOUND4 IMPACT, FIRST, PULSE, and Eco products running version 2.x. This flaw enables attackers to bypass authorization controls and access hidden system resources by manipulating user-supplied input, allowing the execution of privileged functionalities without proper authentication. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility, low complexity, and high potential impact on confidentiality, integrity, and availability.
Remote attackers require no privileges, authentication, or user interaction to exploit the vulnerability. By altering user-supplied input, they can directly reference and access unauthorized objects, executing privileged operations that compromise the targeted system.
Advisories from VulnCheck and Zero Science Laboratory (ZSL-2022-5723) detail the authorization bypass via insecure object references in the affected SOUND4 products. An exploit is publicly available on Exploit-DB (ID 51169). No specific patch or mitigation details are provided in the referenced advisories, and the vendor's site is archived via web.archive.org.
The public availability of an exploit on Exploit-DB suggests potential for real-world exploitation, though no confirmed incidents are noted in the provided information.
