CVE-2022-35583 is a critical Server-Side Request Forgery (SSRF) vulnerability affecting wkhtmltopdf version 0.12.6. This vulnerability allows an attacker to gain initial access into the target's system by injecting an iframe tag with an initial asset IP address in its source. The implications of this flaw are severe, as it enables attackers to take over the entire infrastructure by accessing internal assets. With a CVSS score of 9.8, the severity of this vulnerability cannot be overstated.
Organizations using wkhtmltopdf should be aware that this vulnerability is actively exploitable. As such, it requires immediate attention. The potential for unauthorized access to sensitive internal resources could lead to significant operational disruption and data compromise. Organizations should prioritize patching immediately.
The vulnerability was published on August 22, 2022, and has been classified as CWE-918. The risk to organizations includes loss of confidentiality, integrity, and availability of their systems. The attack vector is network-based, with low complexity and no privileges or user interaction required.
Given the critical nature of this vulnerability, organizations must act swiftly to remediate it. The potential for exploitation is high, and failure to address it could result in severe repercussions.
Vulnerability Details
The official description of CVE-2022-35583 states that wkhtmlTOpdf 0.12.6 is vulnerable to SSRF, allowing attackers to gain initial access by injecting an iframe tag with an initial asset IP address on its source. This can lead to a complete takeover of the infrastructure.
The vulnerability has a CVSS score of 9.8, categorized as critical due to its high potential impact on confidentiality, integrity, and availability. The affected product is wkhtmltopdf version 0.12.6, and the vulnerability was disclosed on August 22, 2022.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input in the form of iframe tags. Attackers can exploit this by crafting a specially formatted request to access internal resources that should not be exposed to the public.
The attack vector is network-based, requiring low complexity and no privileges or user interaction. This means that an attacker can exploit the vulnerability without needing to authenticate or interact with the application in any way.
In terms of impact, if exploited, the vulnerability can compromise confidentiality by allowing unauthorized access to sensitive information. The integrity of the system can also be affected, as attackers can manipulate internal resources. Finally, availability may be impacted if the attacker takes control of critical infrastructure components.
Risk & Impact Analysis
The risk to organizations includes significant exposure to unauthorized access, data breaches, and potential operational disruption. Given the critical nature of this vulnerability, organizations should assess their exposure and the potential blast radius if exploited.
Organizations should prioritize patching immediately. The ability for an attacker to access internal assets can lead to catastrophic outcomes, including full infrastructure compromise.
