CVE-2022-45064 is a high-severity vulnerability affecting the Apache Sling Engine. This vulnerability allows attackers to exploit include-based cross-site scripting (XSS) issues due to improper implementation of the RequestDispatcher API. The successful exploitation of this vulnerability can lead to privilege escalation to administrative power.
The vulnerability is classified as high due to its potential impact on confidentiality, integrity, and availability. According to the CVSS scoring system, it has a score of 8, indicating a high level of severity that organizations should not overlook.
Risk to organizations includes unauthorized access to sensitive data and administrative control over affected systems. The vulnerability is network-exploitable and requires low privileges and user interaction. Therefore, organizations must prioritize patching immediately.
Apache has recommended updating to version 2.14.0 or later of the Apache Sling Engine and enabling the "Check Content-Type overrides" configuration option to mitigate the risk associated with this vulnerability.
As of now, no public exploits have been confirmed, but organizations must remain vigilant and ensure they are on the latest version to avoid potential exploitation.
Vulnerability Details
The vulnerability arises from the SlingRequestDispatcher's failure to properly implement the RequestDispatcher API, leading to a generic type of include-based cross-site scripting issues. It is exploitable by an attacker who can include a resource with a specific content-type and control the include path.
The vulnerability was published on April 13, 2023, and is categorized under CWE-79, which pertains to improper neutralization of input during web page generation.
Organizations running Apache Sling Engine versions prior to 2.14.0 are affected and should apply the patch immediately.
Technical Analysis
The root cause of this vulnerability is the improper handling of requests within the SlingRequestDispatcher. As a result, attackers can craft requests that manipulate the server's response, leading to XSS.
The attack vector is network-based, which increases the risk as it can be executed remotely. The complexity of the attack is high, requiring an attacker to have knowledge of the server's configurations and the ability to craft specific requests. It also requires low privileges and user interaction, as the attacker needs to get a user to trigger the vulnerable functionality.
The impacts include high confidentiality, integrity, and availability risks, making it critical for organizations to assess their exposure and apply the necessary patches.
Risk & Impact Analysis
With the potential for severe consequences, organizations must understand the risks associated with CVE-2022-45064. The vulnerability allows an attacker to escalate privileges, which can lead to unauthorized access to sensitive information and critical systems. The blast radius of such an exploit could be significant, impacting not just the affected application but potentially the entire infrastructure.
Organizations should address this vulnerability in their priority patch cycle. The urgency is heightened by the fact that the vulnerability is classified as high severity, and while no public exploits are currently known, the potential for exploitation remains.
