Threat metrics

Exploit Maturity: POC

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 26 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Immediately isolate and monitor all instances of wvp-GB28181-pro versions 2.7.0 through 2.7.4 to detect suspicious API requests indicative of deserialization attacks.
Implement network-level access controls restricting inbound traffic to the API endpoint only from trusted sources and management networks.
Employ Web Application Firewalls (WAFs) with custom rules to detect and block malicious serialized payloads targeting FastJson deserialization patterns.
Where feasible, disable or replace the vulnerable GenericFastJsonRedisSerializer component with safer serialization libraries or configurations that enforce strict input validation and type whitelisting.
Conduct thorough code reviews and penetration testing focused on deserialization vectors in the affected software.
Maintain strict logging and alerting on deserialization errors or anomalies in Redis interactions.
Engage with the vendor or community for updates or unofficial patches, and plan for upgrade or migration to patched versions once available.
Educate security teams about this vulnerability and prepare incident response plans for potential exploitation scenarios.
Consider deploying runtime application self-protection (RASP) solutions to detect and block exploitation attempts in real time.

Description

A security flaw has been discovered in 648540858 wvp-GB28181-pro up to 2.7.4. This affects the function GenericFastJsonRedisSerializer of the file src/main/java/com/genersoft/iot/vmp/conf/redis/RedisTemplateConfig.java of the component API Endpoint. The manipulation results in deserialization. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The vulnerability allows remote attackers to exploit insecure deserialization in a critical API component, potentially leading to unauthorized code execution or manipulation of system data. This can compromise the confidentiality of sensitive video streams or configuration data, integrity of system operations, and availability of the video management service. Organizations relying on wvp-GB28181-pro for surveillance or IoT device management could face service disruptions, data breaches, or lateral movement by attackers. The lack of authentication and user interaction requirements lowers the barrier to exploitation, increasing risk. Although the CVSS score is medium, the impact on critical infrastructure such as security monitoring systems could be significant. The public availability of exploit code further elevates the threat, increasing the likelihood of opportunistic attacks. The absence of vendor patches means organizations must rely on alternative mitigations to reduce exposure.
