Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2023-36478)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow in MetaDataBuilder.checkSize when handling HTTP/2 HPACK header values. A remote attacker can send specially crafted request to the server, trigger an integer overflow and crash the server.
2) Resource exhaustion (CVE-ID: CVE-2023-44487)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".
Note, the vulnerability is being actively exploited in the wild.
3) Improper input validation (CVE-ID: CVE-2023-22045)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
The vulnerability exists due to improper input validation within the Hotspot component in Oracle GraalVM for JDK. A remote non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.
4) Improper input validation (CVE-ID: CVE-2023-22049)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the Libraries component in Oracle GraalVM for JDK. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
5) Improper input validation (CVE-ID: CVE-2023-22081)
The vulnerability allows a remote non-authenticated attacker to perform service disruption.
The vulnerability exists due to improper input validation within the JSSE component in Oracle GraalVM for JDK. A remote non-authenticated attacker can exploit this vulnerability to perform service disruption.
6) Improper input validation (CVE-ID: CVE-2023-22067)
The vulnerability allows a remote non-authenticated attacker to manipulate data.
The vulnerability exists due to improper input validation within the CORBA component in Oracle Java SE. A remote non-authenticated attacker can exploit this vulnerability to manipulate data.
7) Segmentation fault (CVE-ID: CVE-2023-5676)
The vulnerability allows a local privileged user to perform a denial of service (DoS) attack.
The vulnerability exists due to JVM can be forced into an infinite busy hang on a spinlock or a segmentation fault if a shutdown signal (SIGTERM, SIGINT or SIGHUP) is received before the JVM has finished initializing. A local privileged user can pass specially crafted input to the application and perform a denial of service (DoS) attack.
8) Cross-site request forgery (CVE-ID: CVE-2023-45857)
The vulnerability allows a remote attacker to perform cross-site request forgery attacks.
The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.
9) Improper Authorization (CVE-ID: CVE-2023-41900)
The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to an error in the revocation process. If a Jetty OpenIdAuthenticator uses the optional nested LoginService, and that LoginService decides to revoke an already authenticated user, then the current request will still treat the user as authenticated.
10) 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.
11) 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.
12) Improper access control (CVE-ID: CVE-2018-8088)
The vulnerability allows a remote unauthenticated attacker to bypass access restrictions on the target system.The weakness exists in the org.slf4j.ext.EventData class due to improper security restrictions. A remote attacker can send specially crafted input, bypass access restrictions and gain unauthorized access to perform further attacks.
