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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Detectable: no evidence on record.
No public nuclei template indexed

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), 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.

What to do

AI-suggested

Immediately restrict network access to the /function/system/basic/license_update.php endpoint by implementing firewall rules or network segmentation to limit exposure to trusted management networks only.
Monitor network traffic and logs for unusual or unauthorized requests targeting the license_update.php endpoint, employing intrusion detection/prevention systems (IDS/IPS) with updated signatures.
Engage with the DCME product vendor to obtain official patches or security updates as soon as they become available and apply them promptly.
If patches are not yet available, consider temporary workarounds such as disabling the license update functionality if feasible without disrupting operations.
Conduct thorough audits of affected systems to detect any signs of compromise or unauthorized access.
Implement strict access controls and multi-factor authentication on management interfaces to reduce the attack surface.
Educate security teams about this vulnerability to ensure rapid response capability upon detection of exploitation attempts.
Maintain up-to-date backups and incident response plans to minimize damage in case of successful exploitation.

Description

DCME-320 <=7.4.12.90, DCME-520 <=9.25.5.11, DCME-320-L, <=9.3.5.26, and DCME-720 <=9.1.5.11 are vulnerable to Remote Code Execution via /function/system/basic/license_update.php.

Impact

The potential impact of CVE-2024-52777 is severe for organizations worldwide using the affected DCME products. Exploitation can lead to complete system compromise, allowing attackers to execute arbitrary commands, install malware, exfiltrate sensitive data, or disrupt critical services. Given the vulnerability requires no authentication and no user interaction, attackers can remotely target exposed systems with minimal effort. This can result in widespread operational outages, data breaches, and potential lateral movement within enterprise networks. Organizations in sectors relying on DCME products for network or industrial control management face heightened risks of sabotage or espionage. The criticality of the vulnerability also increases the likelihood of rapid exploitation once exploit code becomes publicly available, potentially leading to large-scale attacks. The absence of known exploits currently provides a narrow window for proactive defense, but the high CVSS score underscores the urgency of mitigation.
