Published: 22 June 2023
Summary
CVE-2023-29708 is a high-severity Incorrect Authorization (CWE-863) vulnerability in Wavlink Wavrouter App. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 9.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2023-29708 is an unauthenticated remote command issue located in the /cgi-bin/adm.cgi endpoint of WavLink WavRouter firmware version RPT70HA1.x. The flaw permits an attacker to submit a specially crafted payload that forces the device to perform a factory reset, classified under CWE-863 with a CVSS 3.1 base score of 7.5 reflecting network attack vector, low complexity, and high availability impact.
An unauthenticated attacker with network access can send the malicious request to the web management interface, causing the router to erase all configuration settings and reboot into a default state. This results in immediate denial of service for connected users and requires physical or administrative intervention to restore prior settings.
Public references consist of proof-of-concept disclosures on GitHub and a Notion page; neither source nor the CVE record itself describes vendor patches, firmware updates, or recommended mitigations. The associated EPSS score has remained flat at 0.0575 since publication, indicating no observable increase in in-the-wild exploitation interest.

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.
Periodic review and update of procedures reduces incorrect authorization implementations over time.
Supervision identifies cases where authorization logic incorrectly permits unauthorized actions.
Defining permitted attribute values and auditing modifications reduces the chance of incorrect authorization outcomes due to tampered or missing labels.
The authorization process and usage restrictions help prevent incorrect authorization for remote access types.
Establishing configuration and connection requirements helps ensure correct rather than incorrect authorization for wireless access.
Establishing connection authorization processes for mobile devices helps ensure authorization decisions are correctly implemented rather than incorrect.
Monitoring account use, notifying on changes, and reviewing accounts for compliance corrects incorrect authorization assignments.
Ensures authorization decisions for external system use are correctly implemented and enforced.
