Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2025-58057)
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 BrotliDecoder and some other decompressing decoders. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2025-58056)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP/1.1 requests. 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.
3) Resource exhaustion (CVE-ID: CVE-2025-55163)
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 when handling HTTP/2 requests. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
4) Uncontrolled Recursion (CVE-ID: CVE-2025-48924)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to the methods ClassUtils.getClass(...) can throw StackOverflowError on very long inputs. Because an Error is usually not handled by applications and libraries, a StackOverflowError could cause an application to stop. A remote attacker can trigger uncontrolled recursion and perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2025-1634)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists in in the quarkus-resteasy extension due to application does not properly control consumption of internal resources when client requests with low timeouts are made. A remote user can trigger resource exhaustion and perform a denial of service (DoS) attack.
6) Exposure of Resource to Wrong Sphere (CVE-ID: CVE-2025-49574)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to an error when duplicating a duplicated context. A remote user can gain access to sensitive information, such as request scope, security details, and metadata.
7) Improper authentication (CVE-ID: CVE-2024-56128)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in Salted Challenge Response Authentication Mechanism (SCRAM) implementation. The application does not verify that the nonce sent by the client in the second message matches the nonce sent by the server in its first message. A remote attacker with access to plain text SCRAM authentication exchange can bypass forge the second once and gain unauthorized access to the application.
8) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2025-27817)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input in Apache Kafka Client. The application accepts configuration data for setting the SASL/OAUTHBEARER connection with the brokers, including "sasl.oauthbearer.token.endpoint.url" and "sasl.oauthbearer.jwks.endpoint.url". A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
9) Deserialization of Untrusted Data (CVE-ID: CVE-2025-27819)
The vulnerability allows a remote attacker to perform a denial of service attack.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and perform a denial of service attack.
10) Deserialization of Untrusted Data (CVE-ID: CVE-2025-27818)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote user can set the sasl.jaas.config property for connector's Kafka clients to 'com.sun.security.auth.module.LdapLoginModule' through various override properties (producer.override.sasl.jaas.config, consumer.override.sasl.jaas.config, or admin.override.sasl.jaas.config). This configuration enables the server to connect to an attacker's LDAP server and deserialize the LDAP response, potentially leading to the execution of java deserialization gadget chains on the Kafka connect server.
11) Files or Directories Accessible to External Parties (CVE-ID: CVE-2025-11965)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the files or directories accessible to external parties in the hidden file protection feature of "StaticHandler" when "setIncludeHidden(false)" is configured. A remote attacker can gain access to sensitive information on the system.
12) Stored cross-site scripting (CVE-ID: CVE-2025-11966)
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 directory listings within file names. A remote user can inject 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.
