Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 36% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Citrix ADC and Citrix Gateway contain an arbitrary file read vulnerability identified as CVE-2023-24487. The flaw received a CVSS 3.1 base score of 6.3 and is associated with CWE-253. It affects the network-adjacent attack surface of these appliances and was publicly disclosed on 10 July 2023.
An unauthenticated attacker positioned on an adjacent network can exploit the issue without user interaction. Successful exploitation permits limited disclosure of file contents along with limited integrity and availability impacts on the affected appliance.
Citrix has published security bulletin CTX477714 that addresses both CVE-2023-24487 and the related CVE-2023-24488, directing customers to the corresponding software updates and configuration guidance for remediation. The EPSS score for this CVE has remained in the 0.32–0.36 range without a pronounced increase after disclosure.

Secure SDLC mandates return-value checks and error handling, directly reducing CWE-253.
A.8.26 requires that security requirements (including input validation, resilience against injections, output controls, error handling, etc.) be identified and specified during development or acquisition; it does not itself enforce, implement or assure correct checking of function return values and therefore does not stop exploitation of CWE-253 defects that remain present.
A.8.27 establishes and applies secure engineering principles (e.g. least privilege, security by design, distrust external input, fail securely) and requires design reviews against known attack patterns; CWE-253 is a specific code-level implementation error in checking function returns that these principles and reviews do not stop from being introduced or exploited.
Secure coding explicitly demands checking return values, covering most of CWE-253.
Security testing in development catches missing or incorrect return-value checks.
