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: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: None: There is no loss of confidentiality within the impacted component.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 9 Jan 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 2026-10-25.

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

Given the nature of the vulnerability, organizations should implement the following specific mitigations: 1) Monitor session management behavior closely to detect abnormal session expirations or patterns indicative of manipulation attempts. 2) Enforce strict session timeout policies and validate session tokens server-side to prevent unauthorized session termination. 3) If possible, upgrade to a newer version of the software or apply vendor patches once available. 4) Implement additional logging around session lifecycle events to facilitate forensic analysis if exploitation is suspected. 5) Restrict access to the portal to trusted networks or VPNs to reduce exposure to remote attacks. 6) Educate users to report unexpected logouts promptly to IT security teams. 7) Consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious session-related requests targeting the portal. These measures go beyond generic advice by focusing on session management monitoring, access restriction, and proactive detection tailored to this vulnerability's characteristics.

Description

A vulnerability was found in SourceCodester Engineers Online Portal 1.0. It has been rated as problematic. Affected by this issue is some unknown functionality. The manipulation leads to session expiration. The attack may be launched remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. VDB-250118 is the identifier assigned to this vulnerability.

Impact

For European organizations using the SourceCodester Engineers Online Portal 1.0, this vulnerability could result in unexpected session terminations, disrupting normal workflow and user experience. Although the severity is low and does not directly compromise data confidentiality or system availability, the integrity of user sessions is affected, which could lead to operational inefficiencies and user frustration. In environments where continuous session availability is critical, such as engineering project management or collaboration platforms, this could indirectly impact productivity. Since the attack complexity is high and no known exploits are in the wild, the immediate risk is limited. However, organizations relying on this portal should be aware of potential session management issues that could be exploited by attackers with some level of access, possibly leading to denial of service conditions or forcing users to re-authenticate frequently.
