CVE-2023-2745 is a medium-severity vulnerability that affects WordPress Core versions up to and including 6.2. This vulnerability allows unauthenticated attackers to exploit a Directory Traversal flaw via the ‘wp_lang’ parameter. Attackers may leverage this vulnerability to access and load arbitrary translation files. In scenarios where an attacker can upload a crafted translation file, such as through an upload form, this could also enable a Cross-Site Scripting attack. The severity of this vulnerability, rated at a CVSS score of 5.4, necessitates immediate attention from organizations using affected versions.
The potential for exploitation underscores the risk to organizations, as unauthorized access to sensitive data and functionality can lead to further attacks. Organizations should prioritize patching immediately to prevent exploitation.
As this vulnerability has been classified as high risk based on its exploitability and real-world impact, it is crucial for security teams to assess their environments for affected WordPress installations and to apply recommended patches swiftly.
Despite the moderate severity, the implications of this vulnerability can be significant, particularly for high-profile websites that rely on WordPress for their operations. Organizations are urged to address this in their priority patch cycle.
Vulnerability Details
The official CVE description states: "WordPress Core is vulnerable to Directory Traversal in versions up to, and including, 6.2, via the ‘wp_lang’ parameter. This allows unauthenticated attackers to access and load arbitrary translation files. In cases where an attacker is able to upload a crafted translation file onto the site, such as via an upload form, this could also be used to perform a Cross-Site Scripting attack."
This vulnerability is classified under CWE-22, indicating a directory traversal issue. The CVSS score of 5.4 reflects a medium severity level, highlighting the potential for exploitation without requiring user interaction.
Technical Analysis
The root cause of CVE-2023-2745 lies in insufficient validation of the ‘wp_lang’ parameter, enabling Directory Traversal. The attack vector is network-based, requiring no privileges or user interaction, which significantly increases the risk. The attack complexity is rated as high, meaning successful exploitation may require specific conditions. However, once exploited, attackers can compromise confidentiality and integrity.
The confidentiality impact is categorized as low, indicating that sensitive information could be accessed, while integrity impact is also rated low, as attackers can manipulate content but with limited effects on system functionality. No availability impact is noted.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive translation files, which could lead to further vulnerabilities, including Cross-Site Scripting attacks. The potential blast radius of this vulnerability is broad, particularly for sites that allow user-generated content or file uploads.
Organizations should assess their environments for any instances of WordPress running affected versions and prioritize remediation in their patching cycle. The urgency of addressing this vulnerability is underscored by its CVSS score and the existence of a public exploit, which raises the likelihood of active exploitation.
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
This vulnerability affects all WordPress Core versions prior to 6.2. Organizations should ensure they are running the latest version to mitigate this risk.
Mitigation & Remediation
Organizations should prioritize updating their WordPress installations to version 6.2.1 or later. If immediate patching is not possible, implementing configuration hardening by restricting file upload capabilities and monitoring for unusual file access can help mitigate risks.
For effective remediation, organizations can consider engaging in penetration testing to validate the security posture of their WordPress installations.
Detection Guidance
Organizations should monitor web server logs for unusual access patterns that may indicate exploitation attempts. Key indicators include access to unexpected translation files or unusual file upload activities.
AppSecure Threat Intelligence Insight
CVE-2023-2745 reflects a growing trend in vulnerabilities related to file handling and upload mechanisms within web applications. Security teams should be vigilant about the implications of such vulnerabilities and implement strict controls around file uploads.
The existence of public exploits and proof-of-concept code necessitates a proactive approach to vulnerability management. Organizations should explore resources and best practices for securing their WordPress environments, including regular security assessments and updates.
