CVE-2020-36949
Published: 27 January 2026
Summary
CVE-2020-36949 is a medium-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability in Raimersoft Tapinradio. Its CVSS base score is 6.7 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 27.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation).
Deeper analysis
CVE-2020-36949 is a denial of service vulnerability in TapinRadio version 2.13.7, specifically within the application proxy settings. The flaw allows attackers to crash the program by overflowing input fields, such as pasting a large buffer of 20,000 characters into the username and address fields. This triggers CWE-770 (Allocation of Resources Without Limits or Throttling), rendering the application unresponsive.
The vulnerability carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H), indicating it is exploitable remotely over the network with low attack complexity, no required privileges, and no user interaction. Any unauthenticated attacker can achieve a high-impact denial of service, causing the program to crash and require reinstallation to restore functionality.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
Directly prevents denial-of-service from input overflows by validating the size and format of proxy settings fields like username and address.
Enforces limits on input quantities, such as maximum character lengths for proxy username and address fields, to block large buffer overflows.
Protects against remote denial-of-service attacks like this CVE by limiting effects of resource exhaustion in application inputs and detecting such events.
