CVE-2024-7627
Published: 05 September 2024
Summary
CVE-2024-7627 is a high-severity Code Injection (CWE-94) vulnerability in Bitapps File Manager. Its CVSS base score is 8.1 (High).
Operationally, ranked in the top 3.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
The Bit File Manager plugin for WordPress is vulnerable to remote code execution in versions 6.0 to 6.5.5 through the checkSyntax function. The flaw stems from writing a temporary file to a publicly accessible directory before validation completes, enabling code injection under CWE-94 and a race condition under CWE-362.
Unauthenticated attackers can exploit the issue to run arbitrary code on the server when an administrator has granted Guest User read permissions. The vulnerability carries a CVSS 3.1 score of 8.1 reflecting high impact on confidentiality, integrity, and availability despite the high attack complexity.
A fix addressing the temporary-file handling was committed in changeset 3138710 of the plugin repository, with additional details available in the Wordfence advisory for the vulnerability.
The associated EPSS score rose from a low baseline to a peak of 0.3967 before settling at a current value of 0.2856, indicating that exploitation interest emerged after public disclosure.

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.
Accurate timestamps from internal clocks enable detection of race conditions by providing reliable event ordering in audit logs.
Coordination of concurrent security activities reduces the probability that shared resources will be accessed simultaneously without proper synchronization.
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.
