Published: 02 February 2024
Summary
CVE-2024-22899 is a high-severity Code Injection (CWE-94) vulnerability in Vinchin Vinchin Backup And Recovery. Its CVSS base score is 8.8 (High).
Operationally, ranked in the top 4.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Vinchin Backup & Recovery version 7.2 contains an authenticated remote code execution vulnerability in the syncNtpTime function. The flaw is tracked as CVE-2024-22899 with a CVSS 3.1 score of 8.8 and is associated with CWE-94 code injection. It permits an attacker who already possesses valid credentials to execute arbitrary commands on the affected backup server over the network.
An authenticated remote attacker can supply crafted input to the syncNtpTime function and obtain full control of the target system, resulting in complete compromise of confidentiality, integrity, and availability. No user interaction is required and the attack can be launched from an adjacent network position once credentials are obtained.
Public disclosures referenced in the CVE entry, including detailed write-ups on Leakix and Full Disclosure lists, describe the issue as part of a larger RCE chain but do not include official vendor patch information or mitigation guidance. The associated EPSS score has reached a peak of 0.2120 with no reported material rise after publication.

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.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
