CVE-2018-18628 describes an Insecure Deserialization vulnerability affecting Pippo-Core versions up to 1.9.0. This flaw allows attackers to execute arbitrary code on a vulnerable system by manipulating serialized objects within PIPPO_SESSION cookies. The vulnerability was published on October 24, 2018, and a fix is available in version 1.12.0.
The impact of CVE-2018-18628 is severe, enabling remote code execution (RCE). An attacker can craft a malicious serialized object, base64 encode it, and embed it within a PIPPO_SESSION cookie. When a user with the vulnerable Pippo-Core version receives and processes this cookie, the deserialization process will trigger the execution of the attacker's code. This could lead to complete system compromise, data theft, or denial of service. The ease of exploitation, combined with the potential for RCE, makes this a high-priority vulnerability. This vulnerability shares similarities with other deserialization flaws where untrusted data is directly deserialized without proper validation, potentially leading to arbitrary code execution.
CVE-2018-18628 was publicly disclosed on October 24, 2018. While no active exploitation campaigns have been definitively linked to this CVE, the ease of exploitation and the potential for RCE make it a likely target. The vulnerability is not currently listed on the CISA KEV catalog. Public proof-of-concept exploits are available, demonstrating the feasibility of remote code execution.

The primary mitigation for CVE-2018-18628 is to upgrade Pippo-Core to version 1.12.0 or later, which contains the fix. If upgrading is not immediately feasible, consider implementing input validation on the PIPPO_SESSION cookie to prevent the injection of potentially malicious data. While not a complete solution, this can reduce the attack surface. Web application firewalls (WAFs) configured to detect and block deserialization attacks can also provide a layer of defense. Monitor application logs for unusual deserialization activity or errors related to object creation. After upgrading, confirm the fix by attempting to send a known malicious cookie and verifying that it is rejected or handled safely.
