CVE-2022-35737 is a high-severity vulnerability classified under CVSS 3.1 with a score of 7.5. This vulnerability allows an array-bounds overflow in SQLite versions 1.0.12 through 3.39.x before 3.39.2, potentially leading to application crashes or other disruptions if a large string argument is processed using the C API. The vulnerability has been confirmed to affect multiple products including SQLite, NetApp's ONTAP Select Deploy Administration Utility, and Splunk's Universal Forwarder.
The nature of this vulnerability presents a significant risk to organizations using the affected versions. With the attack vector being network-based and requiring no privileges or user interaction, attackers may leverage this weakness to cause availability issues. Organizations should prioritize patching immediately.
As of now, there is no confirmed public exploit; however, the availability of proof-of-concept code on GitHub indicates that the vulnerability can be actively exploited. The urgency for patching is further emphasized by the high exploitability score.
The vulnerability was published on August 3, 2022, and remains significant due to its potential impact on application availability. Organizations should remain vigilant and ensure that they are running updated versions of SQLite.
Vulnerability Details
The official description states: 'SQLite 1.0.12 through 3.39.x before 3.39.2 sometimes allows an array-bounds overflow if billions of bytes are used in a string argument to a C API.' This vulnerability, classified as CWE-129, can have significant consequences if exploited.
The CVSS 3.1 score of 7.5 indicates a high severity level, primarily due to its potential to impact availability. The vulnerability affects various products from vendors such as SQLite, NetApp, and Splunk, which enhances its relevance in many environments.
Technical Analysis
The root cause of this vulnerability arises from inadequate bounds checking when processing string arguments. This allows for an overflow condition if excessively large data is provided, potentially leading to crashes or other types of denial-of-service attacks.
The attack vector is network-based, meaning that an attacker can trigger this vulnerability remotely without needing physical access to the target system. The attack complexity is classified as low, as it does not require special conditions or privileges, making it easier to exploit.
Required privileges are none, and user interaction is also not necessary. The vulnerability impacts availability, as successful exploitation could lead to service interruptions.
Risk & Impact Analysis
Risk to organizations includes the potential for application downtime and loss of availability, given that this vulnerability can be exploited remotely and easily. The blast radius is significant, especially for organizations relying on SQLite for critical operations.
Due to the high CVSS score and the nature of the vulnerability, organizations should address this issue in their priority patch cycle. The urgency is further compounded by the high likelihood of exploitation, as indicated by the availability of proof-of-concept code.
As organizations navigate the complexities of securing their environments, vulnerabilities like CVE-2022-35737 serve as critical reminders of the need for proactive and timely remediation.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
Affected versions include SQLite 1.0.12 through 3.39.x before 3.39.2, as well as specific versions of NetApp's ONTAP Select Deploy Administration Utility and Splunk's Universal Forwarder. Organizations should ensure that all instances of these products are updated to the latest versions to mitigate risk.
Mitigation & Remediation
Organizations should immediately upgrade to SQLite version 3.39.2 or later. For those using NetApp or Splunk products, consult the respective vendor advisories for recommended patches. If patches are not available, consider implementing configuration hardening measures and network controls to limit exposure.
Additionally, organizations can validate the effectiveness of their remediation through penetration testing to identify similar weaknesses.
Detection Guidance
To detect potential exploitation of CVE-2022-35737, organizations should monitor logs for unusual API usage patterns and excessive memory allocation requests. Behavioral anomalies such as unexpected crashes or performance degradation should also be investigated.
AppSecure Threat Intelligence Insight
The emergence of CVE-2022-35737 highlights the ongoing need for robust security practices, especially in environments utilizing SQLite extensively. Organizations should regularly review their software supply chains for vulnerabilities and assess their risk exposure.
As attackers continue to exploit similar vulnerabilities, it is essential for security teams to remain vigilant and proactive in their defenses. Organizations should consider implementing a comprehensive penetration testing methodology to identify and remediate weaknesses before they can be exploited.
Finally, security teams should utilize resources such as vulnerability management programs to ensure ongoing security posture improvement.
