CVE-2023-48749 is a Medium severity vulnerability affecting the Theme Nectar Salient Core plugin, specifically versions from n/a through 2.0.2. This vulnerability allows an attacker to exploit improper neutralization of input during web page generation, leading to stored Cross-site Scripting (XSS). The potential risk to organizations includes unauthorized access to sensitive information, session hijacking, and exploitation of users' trust. Given its nature, it is essential for organizations using this plugin to recognize the urgency of addressing this vulnerability.
With a CVSS score of 6.5, this vulnerability is classified as Medium severity, indicating a moderate level of risk. The attack vector is network-based, with low attack complexity, and it requires low privileges along with user interaction. The scope of the vulnerability is changed, affecting the confidentiality, integrity, and availability of information in a limited manner.
No public exploits or proof of concept code has been confirmed for this vulnerability as of now. However, its presence in a widely used plugin presents a viable target for potential attackers. Thus, organizations should prioritize patching immediately to reduce risks associated with this vulnerability.
Given the ongoing evolution of threats, it is crucial for organizations to remain vigilant and ensure their plugins are updated to the latest versions. Organizations can refer to relevant security advisories for further information on remediation strategies.
Vulnerability Details
The CVE-2023-48749 vulnerability arises from improper input handling during web page generation in the Theme Nectar Salient Core plugin. According to the official description, this vulnerability allows for stored XSS, which can be exploited to inject malicious scripts into web pages viewed by other users.
The CVSS score attributed to this vulnerability is 6.5, indicating a Medium level of risk. The attack vector is classified as network-based, meaning an attacker can exploit this vulnerability remotely. The attack complexity is low, requiring minimal technical skill to exploit.
This vulnerability affects the Salient Core plugin from Theme Nectar, specifically versions from n/a to 2.0.2. It has been assigned CWE-79, which classifies it as a Cross-site Scripting (XSS) vulnerability.
Technical Analysis
The root cause of CVE-2023-48749 lies in the inadequate validation of user input before it is rendered on web pages. This oversight allows attackers to inject malicious scripts that can be executed in the context of other users' browsers, leading to stored XSS vulnerabilities.
The attack vector for this vulnerability is network-based, meaning that an attacker can exploit it from any location without requiring physical access to the target system. The complexity of the attack is low, which means that even individuals with limited technical skills can potentially exploit this vulnerability.
The privileges required to exploit this vulnerability are low, and it necessitates user interaction, as an attacker must trick a user into interacting with the malicious script. The impacts of this vulnerability on confidentiality and integrity are classified as low, while availability is not affected.
Risk & Impact Analysis
The potential risks associated with CVE-2023-48749 are significant. Organizations utilizing the Theme Nectar Salient Core plugin should be aware that attackers could exploit this vulnerability to execute arbitrary scripts in the context of other users' sessions, leading to unauthorized actions and data exposure.
The blast radius of this vulnerability is relatively large due to the widespread use of the Salient Core plugin. Organizations that fail to address this vulnerability may face reputational damage, loss of customer trust, and potential legal ramifications if data is compromised.
Given the CVSS score of 6.5 and the current absence of public exploits, organizations should still treat this vulnerability with urgency. Organizations should prioritize patching immediately to mitigate risks associated with this vulnerability.
