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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 4 Sep 2024
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
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), 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

To mitigate CVE-2024-44820, organizations should take the following specific actions: 1) Immediately identify and isolate the eginfo.php file located at /3/E_bak5.1/upload/ on all ZZCMS installations. 2) Remove or rename the eginfo.php file if it is not required for normal operations to eliminate the attack surface. 3) If the file is necessary, restrict access to it via web server configuration (e.g., using .htaccess rules or firewall rules) to allow only trusted IP addresses or authenticated users. 4) Disable or remove the phpinfo() function call within the eginfo.php script to prevent sensitive information disclosure. 5) Conduct a thorough audit of environment variables and server configuration to ensure no sensitive credentials are exposed. 6) Monitor web server logs for any suspicious access attempts to the vulnerable endpoint. 7) Keep ZZCMS installations updated and monitor vendor advisories for official patches or updates addressing this vulnerability. 8) Implement network-level protections such as Web Application Firewalls (WAFs) to detect and block exploitation attempts targeting this vulnerability.

Description

A sensitive information disclosure vulnerability exists in ZZCMS v.2023 and before within the eginfo.php file located at /3/E_bak5.1/upload/. When accessed with the query parameter phome=ShowPHPInfo, the application executes the phpinfo() function, which exposes detailed information about the PHP environment, including server configuration, loaded modules, and environment variables.

Impact

The primary impact of CVE-2024-44820 is the unauthorized disclosure of sensitive server and PHP environment information. This leakage can provide attackers with valuable intelligence about the server configuration, installed PHP modules, and environment variables, which may include sensitive data such as database credentials or API keys. Such information can facilitate further attacks, including targeted exploitation of known vulnerabilities in specific PHP modules or server components, privilege escalation, or lateral movement within the network. Since the vulnerability requires no authentication and no user interaction, it can be exploited by any remote attacker scanning for vulnerable ZZCMS installations. Organizations using ZZCMS are at risk of having their internal server details exposed, increasing the likelihood of successful follow-up attacks. The exposure does not directly affect system integrity or availability but significantly compromises confidentiality, which is critical for maintaining secure operations.

The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
MITRE discourages mapping vulnerabilities to this broad entry; the root cause is usually a more specific weakness.
Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
