Description
Deserialization of Untrusted Data vulnerability in impleCode eCommerce Product Catalog allows Object Injection. This issue affects eCommerce Product Catalog: from n/a through 3.4.3.
Analysis
Deserialization of untrusted data vulnerability in impleCode eCommerce Product Catalog versions up to 3.4.3 that allows authenticated attackers with high privileges to perform object injection attacks. The vulnerability enables remote code execution or unauthorized data manipulation through malicious serialized objects. While the CVSS score of 7.2 is moderate-to-high, the requirement for high privileges (PR:H) significantly limits real-world exploitability; however, this should not be underestimated in multi-tenant or insider threat scenarios.
Technical Context
This vulnerability stems from unsafe deserialization practices (CWE-502) in the impleCode eCommerce Product Catalog application, likely in PHP or a similar language that supports object serialization. The root cause is the application's failure to validate or sanitize serialized data before unserializing it, allowing an attacker to instantiate arbitrary object types with attacker-controlled properties. This is a classic object injection attack where gadget chains in the application or its dependencies can be leveraged to achieve remote code execution or other malicious outcomes. The affected product is impleCode eCommerce Product Catalog spanning versions from an unspecified baseline through version 3.4.3, suggesting the vulnerability may have existed for an extended period across multiple releases.
Affected Products
impleCode eCommerce Product Catalog versions 3.4.3 and earlier (exact lower bound not specified in description; likely affects all public releases). CPE representation would be: cpe:2.3:a:implecode:ecommerce_product_catalog:*:*:*:*:*:*:*:* with version < 3.4.4. Vendor advisory and patch availability have not been cross-referenced in the provided data; organizations should consult impleCode's official security advisories, GitHub repositories, or vulnerability databases (NVD, Vulners) for specific patch release notes and timelines.
Remediation
1. **Immediate patch**: Upgrade impleCode eCommerce Product Catalog to version 3.4.4 or later once available from the vendor. 2. **Validate against vendor advisory**: Check impleCode's official security bulletin for patch release dates and deployment procedures. 3. **Temporary mitigations** (if patching is delayed): (a) Restrict administrative and high-privilege user access to trusted personnel; implement principle of least privilege. (b) Monitor serialized object handling and deserialization calls in application logs for suspicious patterns. (c) Disable or sandbox the affected module if possible without disrupting core functionality. (d) Implement input validation and type-checking on all deserialization operations. (e) Apply web application firewall (WAF) rules to detect and block malicious serialized payloads. 4. **Long-term**: Consider implementing a deserialization allowlist (whitelist) for safe object types, or migrate to safer serialization formats (JSON) where feasible.
