Summary
CVE-2024-23759 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Gambio Gambio. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Deserialization of Untrusted Data affects the Gambio e-commerce platform through version 4.9.2.0. The flaw resides in the "search" parameter of the Parcelshopfinder/AddAddressBookEntry function and is tracked under CWE-502 and CWE-434, enabling attackers to supply malicious serialized data that results in arbitrary code execution.
Unauthenticated remote attackers can exploit the issue over the network without user interaction or credentials. Successful exploitation grants full control over the application process, allowing arbitrary code to be run with impacts to confidentiality, integrity, and availability as reflected in the CVSS 9.8 score.
The referenced security advisory at https://herolab.usd.de/security-advisories/usd-2023-0046/ addresses the vulnerability. Exploitation probability rose materially after disclosure, reaching a peak EPSS score of 0.7768 on 2025-01-22 before receding to the current value of 0.6711, indicating increased attacker interest in the months following publication.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.
Least functionality restricts the file types and automatic processing capabilities the system will accept.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Hardened configuration baselines can enforce allowed file types and processing rules.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Secure development practices include input validation and file-type restrictions that prevent this weakness.
PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.
