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: 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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
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 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: 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 impacted component 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 impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 17 Apr 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 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-2024-30986, organizations should implement strict input validation and output encoding on the 'price' and 'sname' parameters in the /edit-services-details.php page. Specifically, use context-aware encoding libraries to neutralize any HTML or JavaScript content before rendering user input. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Limit user privileges to the minimum necessary to reduce the attack surface. Monitor web application logs for suspicious input patterns targeting these parameters. If a patch becomes available from the vendor, apply it promptly. In the interim, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block XSS payloads targeting these parameters. Educate users about the risks of clicking unknown links or submitting untrusted forms. Conduct regular security assessments and code reviews to identify and remediate similar vulnerabilities proactively.

Description

Cross Site Scripting vulnerability in /edit-services-details.php of phpgurukul Client Management System using PHP & MySQL 1.1 allows attackers to execute arbitrary code and via "price" and "sname" parameter.

Impact

The impact of CVE-2024-30986 is significant for organizations using the phpgurukul Client Management System, particularly those managing sensitive client information. Successful exploitation can lead to the execution of arbitrary JavaScript in users' browsers, enabling attackers to steal session cookies, perform actions on behalf of authenticated users, or redirect users to malicious sites. This compromises confidentiality and integrity of data and can disrupt availability if attackers deface or manipulate the CMS interface. Given the scope change in the CVSS vector, the vulnerability could affect multiple users or components beyond the initially targeted user. Organizations relying on this CMS for client management may face reputational damage, regulatory compliance issues, and operational disruptions. The requirement for user interaction and low privileges reduces the ease of exploitation but does not eliminate risk, especially in environments with many users or where social engineering can be employed. The absence of known exploits in the wild currently limits immediate widespread impact but does not preclude future exploitation.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide…
