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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within 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 1 Aug 2025
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-26.

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

1. Immediate patching or upgrading to a fixed version of the code-projects Document Management System is the most effective mitigation; if a patch is unavailable, consider disabling or restricting access to the vulnerable /dell.php endpoint. 2. Implement strict input validation and sanitization on the 'ID' parameter to prevent path traversal sequences such as '../'. 3. Employ web application firewalls (WAFs) configured to detect and block path traversal patterns targeting the unlink function or the /dell.php script. 4. Restrict file system permissions for the web server user to the minimum necessary, preventing deletion of critical system files even if the vulnerability is exploited. 5. Network segmentation and limiting access to the DMS management interfaces to trusted internal networks or VPNs can reduce exposure. 6. Monitor logs for suspicious requests targeting /dell.php or unusual file deletion activities. 7. Regularly back up critical documents and system files to enable recovery in case of successful exploitation. 8. Conduct security assessments and code reviews focusing on input handling in custom scripts like /dell.php to identify and remediate similar vulnerabilities.

Description

A vulnerability was found in code-projects Document Management System 1.0 and classified as critical. This issue affects the function unlink of the file /dell.php. The manipulation of the argument ID leads to path traversal. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using code-projects Document Management System version 1.0, this vulnerability poses a risk primarily to system availability and integrity. Successful exploitation could result in deletion of critical documents or system files, causing operational disruptions and potential data loss. This is particularly impactful for sectors relying heavily on document management for compliance, legal, or operational continuity such as finance, healthcare, and government agencies. The ability to remotely exploit without authentication increases the risk of automated attacks or exploitation by opportunistic threat actors. Additionally, organizations with poor network segmentation or exposed management interfaces are at heightened risk. While confidentiality is not directly impacted, the loss or corruption of documents could indirectly affect data integrity and trustworthiness. Recovery may require restoring files from backups, which could be time-consuming and costly. The medium severity rating suggests that while the threat is significant, it is not critical, but it should not be ignored given the potential operational impact.
