CVE-2025-62035 is a deserialization of untrusted data vulnerability found in uxper's Togo product, affecting versions prior to 1.0.4. Deserialization vulnerabilities occur when software deserializes data from untrusted sources without sufficient validation, allowing attackers to manipulate serialized objects to execute arbitrary code, escalate privileges, or cause denial of service. This vulnerability is remotely exploitable over the network (AV:N) with low attack complexity (AC:L) and requires low privileges (PR:L), but no user interaction (UI:N). The scope is unchanged (S:U), meaning the impact is confined to the vulnerable component. The vulnerability impacts confidentiality, integrity, and availability (C:H/I:H/A:H), indicating that successful exploitation can lead to full system compromise. While no public exploits are currently known, the high CVSS score (8.8) reflects the serious risk posed. The lack of available patches at the time of reporting increases exposure. The vulnerability likely arises from insecure deserialization logic within Togo's data handling mechanisms, which attackers could leverage to inject malicious payloads during object deserialization. This could lead to remote code execution, data breaches, or service disruption.

For European organizations, exploitation of this vulnerability could result in severe consequences including unauthorized access to sensitive data, system takeover, and disruption of critical services. Organizations using Togo in sectors such as finance, healthcare, government, or critical infrastructure could face data breaches, operational downtime, and regulatory penalties under GDPR. The ability to remotely exploit the vulnerability without user interaction increases the risk of automated attacks and worm-like propagation within networks. Given the low privilege requirement, attackers who gain limited access to the network could escalate privileges and compromise entire systems. This could undermine trust in affected services and cause significant financial and reputational damage. The absence of known exploits currently provides a window for proactive mitigation, but the high severity demands immediate attention to prevent future attacks.

1. Apply security patches or updates from uxper as soon as they become available to address CVE-2025-62035. 2. Until patches are released, restrict network access to Togo services using firewalls and network segmentation to limit exposure. 3. Implement strict input validation and deserialization controls, such as using allowlists for classes during deserialization or employing safer serialization libraries. 4. Monitor network traffic and logs for unusual activity indicative of exploitation attempts, including unexpected serialized data or anomalous remote connections. 5. Employ application-layer firewalls or runtime application self-protection (RASP) solutions to detect and block malicious deserialization payloads. 6. Conduct security audits and code reviews focusing on deserialization logic within Togo deployments. 7. Educate system administrators and security teams about the vulnerability and recommended response procedures. 8. Develop and test incident response plans specific to potential exploitation scenarios involving Togo.
