CVE-2022-37255
Published: 16 April 2023
Summary
CVE-2022-37255 is a high-severity Use of Hard-coded Credentials (CWE-798) vulnerability in Tp-Link Tapo C310 Firmware. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 7.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
TP-Link Tapo C310 cameras running firmware version 1.3.0 contain a hard-coded credential pair (username "---" and password "TPL075526460603") that grants access to the RTSP video stream. The flaw is tracked as CVE-2022-37255 with a CVSS 3.1 score of 7.5 and is classified under CWE-798. It resides in the RTSP server component and can be reached over the network without any prior authentication.
An unauthenticated remote attacker can connect directly to the RTSP endpoint using the embedded credentials and retrieve live video without owner interaction or additional privileges. Successful exploitation yields full confidentiality impact on the camera feed while leaving integrity and availability untouched.
The EPSS score rose from a low baseline to a peak of 0.1199 before receding to its current value of 0.0927, indicating measurable post-disclosure interest. Public references consist of a Packet Storm disclosure detailing the unauthorized stream access and links to the vendor site, though no specific firmware remediation steps are provided in the available references.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Enables users to notice when hard-coded credentials have been exploited for unauthorized access.
Security training explicitly warns against hard-coded credentials, lowering their use in systems.
Policy and procedures prohibit hard-coded credentials in favor of managed authentication.
External identity providers eliminate the need for hard-coded credentials in applications.
Changing default authenticators prior to first use and protecting content prevents use of hard-coded credentials.
Central credential stores and rotation policies remove the need for hard-coded credentials in configuration files or code.
Intelligence programs surface reports of campaigns that abuse hard-coded credentials in products, prompting removal or replacement and thereby reducing successful exploitation.
Planned investment enables secure credential storage and management systems instead of hard-coded credentials.
