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: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 20 Nov 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
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 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-2024-48535, organizations should implement strict input validation on the Name parameter to reject or sanitize any HTML or script content before storage. Employing context-aware output encoding when rendering user-supplied data in web pages is critical to prevent script execution. Deploying a robust Content Security Policy (CSP) can further restrict the execution of unauthorized scripts. Access controls should be reviewed to minimize the number of users who can submit data that is stored and displayed to others. Regular security audits and code reviews focusing on input handling can identify similar issues proactively. Monitoring web application logs for unusual input patterns or error messages may help detect attempted exploitation. Until an official patch is released, consider applying virtual patching via web application firewalls (WAFs) configured to detect and block XSS payloads targeting the Name parameter. User awareness training about phishing and suspicious links can reduce the risk of triggering malicious scripts. Finally, maintain an incident response plan to quickly address any detected exploitation attempts.

Description

A stored cross-site scripting (XSS) vulnerability in eSoft Planner 3.24.08271-USA allows attackers to execute arbitrary web scripts or HTML via injecting a crafted payload into the Name parameter.

Impact

The primary impact of CVE-2024-48535 is on the confidentiality and integrity of user data within eSoft Planner environments. Successful exploitation could allow attackers to hijack user sessions, steal sensitive information, or alter displayed content, potentially leading to unauthorized access or misinformation. Although availability is not directly affected, the trustworthiness of the application and user confidence could be severely undermined. Organizations relying on eSoft Planner for planning and scheduling may face operational disruptions if users are compromised or data integrity is questioned. The requirement for some level of privilege to inject the payload limits the attack surface but does not eliminate risk, especially in environments with many users or weak internal controls. The absence of known exploits suggests a window for remediation before widespread attacks occur, but also means defenders must be vigilant. Overall, the vulnerability poses a moderate risk to organizations, particularly those with sensitive or regulated data handled via eSoft Planner.

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.
