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: High: The successful attack depends on the evasion or circumvention of security-enhancing techniques in place that would otherwise hinder the attack. These include: Evasion of exploit mitigation techniques, for example, circumvention of address space randomization (ASLR) or data execution prevention (DEP) must be performed for the attack to be successful; Obtaining target-specific secrets. The attacker must gather some target-specific secret before the attack can be successful. A secret is any piece of information that cannot be obtained through any amount of reconnaissance. To obtain the secret the attacker must perform additional attacks or break otherwise secure measures (e.g. knowledge of a secret key may be needed to break a crypto channel). This operation must be performed for each attacked target.
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: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within 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.

Exploitation evidence

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

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

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 2026-10-26.

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 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

European organizations should prioritize upgrading elunez eladmin to a version that replaces or removes the use of DES encryption in EncryptUtils, ideally moving to modern, secure encryption algorithms such as AES with strong key management. If an official patch is not yet available, organizations should implement compensating controls, including restricting network access to eladmin administrative interfaces to trusted IP ranges and enforcing strong authentication and monitoring to detect anomalous access attempts. Additionally, reviewing and rotating any credentials or sensitive data encrypted with the affected mechanism is advisable to limit exposure. Security teams should conduct thorough code audits and penetration testing focused on encryption handling within eladmin deployments. Logging and alerting should be enhanced to detect potential exploitation attempts. Finally, organizations should maintain close communication with the vendor for timely patch releases and apply updates promptly once available.

Description

A vulnerability was identified in elunez eladmin up to 2.7. Affected by this vulnerability is the function EncryptUtils of the file eladmin-common/src/main/java/me/zhengjie/utils/EncryptUtils.java of the component DES Key Handler. The manipulation of the argument STR_PARAM with the input Passw0rd leads to inadequate encryption strength. The attack can be initiated remotely. The attack is considered to have high complexity. The exploitation appears to be difficult.

Impact

For European organizations using elunez eladmin versions 2.0 to 2.7, this vulnerability poses a moderate risk primarily to the confidentiality of sensitive data encrypted using the affected DES-based mechanism. While the attack complexity is high and exploitation is difficult, successful exploitation could allow remote attackers to decrypt or weaken the protection of sensitive information such as passwords or configuration data. This could lead to unauthorized data disclosure or facilitate further attacks if attackers gain insights into system credentials or secrets. Given that eladmin is an administrative platform, compromised encryption could undermine trust in system integrity and confidentiality, potentially affecting compliance with European data protection regulations such as GDPR. However, the lack of impact on integrity and availability reduces the risk of system disruption or data tampering. The absence of known exploits in the wild lowers immediate urgency but does not eliminate the risk, especially for organizations with high-value targets or sensitive data processed by eladmin. Organizations should consider the potential reputational and regulatory consequences of data exposure resulting from this vulnerability.
