Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Path traversal (CVE-ID: CVE-2022-23457)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in getValidDirectoryPath. A remote attacker can send a specially crafted HTTP request and allow control-flow bypass checks to be defeated.
2) Cross-site scripting (CVE-ID: CVE-2022-24891)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in org.owasp.esapi:esapi. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
3) Integer overflow (CVE-ID: CVE-2022-22976)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to integer overflow in BCrypt class with the maximum work factor (31) for BCryptPasswordEncoder. The encoder does not perform any salt rounds, which weakens encryption capabilities of the software.
4) Improper Authorization (CVE-ID: CVE-2022-22978)
The vulnerability allows a remote attacker to bypass authorization process.
The vulnerability exists due to input validation error when processing untrusted input in applications that are using RegexRequestMatcher with `.` in the regular expression. A remote non-authenticated attacker can bypass authorization checks.
