CVE-2022-24775 is a high-severity vulnerability affecting the GuzzlePHP PSR-7 HTTP message library. This vulnerability allows improper header parsing in versions prior to 1.8.4 and 2.1.1. An attacker could exploit this issue by sneaking in a new line character, which could lead to the passing of untrusted values. The issue has been patched in versions 1.8.4 and 2.1.1, and as of now, there are no known workarounds.
The CVSS score for this vulnerability is 7.5, which categorizes it as high severity. This level of risk indicates that organizations using affected versions should act promptly to address the vulnerability, particularly since exploitation can occur over the network and requires no user interaction.
Given the nature of the vulnerability, the risk to organizations includes potential unauthorized manipulation of data, which could have significant implications for data integrity. With the vulnerability being actively discussed in the security community, it is crucial for organizations to prioritize patching immediately.
Currently, there are no public exploits known for this vulnerability, but the potential for exploitation exists, necessitating a strong response from security teams.
Vulnerability Details
The vulnerability allows for improper header parsing, which can lead to attackers injecting untrusted values into HTTP headers. The affected product is the GuzzleHTTP PSR-7 library, specifically versions before 1.8.4 and 2.1.1. The issue was published on March 21, 2022, and has been documented under CWE-20, indicating improper input validation.
Technical Analysis
The root cause of this vulnerability stems from improper parsing of HTTP headers, where an attacker can introduce new line characters. This exploitation can occur over the network with low attack complexity, requiring no privileges or user interaction. The attack's impact is primarily on data integrity, as unauthorized data manipulation may occur, but it has no effect on confidentiality or availability.
Risk & Impact Analysis
Organizations using affected versions of GuzzlePHP's PSR-7 library are exposed to risks that could lead to data integrity issues. Given the high CVSS score of 7.5, this vulnerability should be treated as a priority for remediation. The exploitation of this vulnerability could have a broad impact on applications relying on the GuzzleHTTP library, necessitating immediate patching.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerable versions of the GuzzleHTTP PSR-7 library include all versions prior to 1.8.4 and any version before 2.1.1. Additionally, Drupal versions between 8.0.0 to 9.2.15 and 9.3.0 to 9.3.8 are also affected.
Mitigation & Remediation
Organizations should prioritize updating to GuzzleHTTP PSR-7 versions 1.8.4 or 2.1.1 to mitigate this vulnerability. If immediate patching is not feasible, implementing strict input validation can help reduce the risk, although this is not a complete solution. Regular security assessments and utilizing services like penetration testing can also provide insights into the security posture and potential vulnerabilities in the applications.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual HTTP header values or patterns indicative of header injection attempts. Behavioral anomalies in application performance or user access patterns may also signal exploitation attempts that require further investigation.
AppSecure Threat Intelligence Insight
