Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2023-20861)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of SpEL expressions. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2023-20863)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input. A remote user can use a specially crafted SpEL expression and perform a denial of service (DoS) attack.
3) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-40167)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests when handling the "+" character passed via the HTTP/1 header field. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
4) Resource exhaustion (CVE-ID: CVE-2023-6481)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in logback receiver component. A remote attacker can send send poisoned data, trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Improper Neutralization of HTTP Headers for Scripting Syntax (CVE-ID: CVE-2023-29406)
The vulnerability allows a remote attacker to perform spoofing attack.
The vulnerability exists due to improper input validation in HTTP/1 client when handling HTTP Host header. A remote non-authenticated attacker can send a specially crafted HTTP request with a maliciously crafted Host header and inject additional headers or entire requests.
Successful exploitation of the vulnerability may allow an attacker to perform cross-site scripting, cache poisoning or session hijacking attacks.
6) Integer overflow (CVE-ID: CVE-2023-34454)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in compress. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
7) Integer overflow (CVE-ID: CVE-2023-34453)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in shuffle. A remote attacker can pass specially crafted data to the application, trigger integer overflow and cause a denial of service condition on the target system.
8) Improper Certificate Validation (CVE-ID: CVE-2023-29409)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to verifying certificate chains containing large RSA keys is slow. A remote attacker can cause a client/server to expend significant CPU time verifying signatures.
9) Input validation error (CVE-ID: CVE-2023-36479)
The vulnerability allows a remote user to compromise the affected system.
The vulnerability exists due to insufficient validation of user-supplied input in org.eclipse.jetty.servlets.CGI Servlet when quoting a command before its execution. A remote user can force the application to execute arbitrary file on the server and potentially compromise the system.
