Description
This security bulletin contains information about 20 secuirty vulnerabilities.
1) Inefficient regular expression complexity (CVE-ID: CVE-2025-5889)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions. A remote user can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
2) Improper Handling of Unexpected Data Type (CVE-ID: CVE-2025-7339)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote attacker can inadvertently modify response headers when an array is passed to `response.writeHead()`
3) Double free (CVE-ID: CVE-2025-8058)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the regcomp() function in case previous memory allocations fail. A remote attacker can pass specially crafted data to the application, trigger double free error and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) NULL pointer dereference (CVE-ID: CVE-2024-8006)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the pcap_findalldevs_ex() function in pcap.c. A local user can perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2025-48989)
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 send specially crafted HTTP request to the web server and consume all available memory resources, leading to a denial of service.
Note, this vulnerability is known as HTTP/2 Made You Reset Attack.
6) Improper input validation (CVE-ID: CVE-2024-50609)
The vulnerability allows a remote privileged user to perform a denial of service (DoS) attack.
The vulnerability exists due to improper input validation within the Core (fluentbit) component in Oracle Communications Unified Assurance. A remote privileged user can exploit this vulnerability to perform a denial of service (DoS) attack.
7) Path traversal (CVE-ID: CVE-2025-27210)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to input validation error when processing directory traversal sequences affecting Windows device names like CON, PRN, and AUX. A local user can escalate privileges on the system.
Note, this vulnerability exists due to incomplete fix for #VU103223 (CVE-2025-23084).
8) Infinite loop (CVE-ID: CVE-2025-5399)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop within the WebSocket code. A malicious web server can send a specially crafted packet to the libcurl application and perform a denial of service (DoS) attack.
9) Resource exhaustion (CVE-ID: CVE-2025-27533)
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 during unmarshalling of OpenWire commands. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
10) 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.
11) Uncontrolled Recursion (CVE-ID: CVE-2025-53864)
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. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack via a deeply nested JSON object supplied in a JWT claim set.
12) Authentication Bypass by Spoofing (CVE-ID: CVE-2024-51504)
The vulnerability allows a remote attacker to bypass IP-based authentication.
The vulnerability exists due to IPAuthenticationProvider is using the X-Forwarded-For HTTP header when authenticated users by IP address in the Admin Server. A remote attacker can pass a trusted IP addresses via the X-Forwarded-For HTTP header and gain unauthorized access to the application.
13) Buffer overflow (CVE-ID: CVE-2025-52999)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when parsing deeply nested JSON files. A remote attacker can pass a specially crafted JSON file to the application, trigger memory corruption and perform a denial of service (DoS) attack.
14) Expected behavior violation (CVE-ID: CVE-2025-54090)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to an error in code that causes the "RewriteCond expr" to be always "true". A remote attacker can bypass implemented security restrictions that rely on regular expressions.
15) Input validation error (CVE-ID: CVE-2024-35164)
The vulnerability allows a remote user to compromise the affected system.
The vulnerability exists in terminal emulator due to insufficient validation of console codes received from servers via text-based protocols like SSH. A remote user can pass specially crafted input to the application and execute arbitrary code with privileges of the running guacd process.
16) Path traversal (CVE-ID: CVE-2025-4517)
The vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to input validation error in the tarfile module when extracting files from an archive with filter="data". A remote attacker can pass specially crafted archive to the application and write files to arbitrary locations on the system outside the extraction directory.
17) Improper access control (CVE-ID: CVE-2025-48734)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions to enum properties. If an application using Commons BeanUtils passes property paths from an external source directly to the getProperty() method of PropertyUtilsBean, an attacker can access the enum’s class loader via the “declaredClass” property available on all Java “enum” objects. Accessing the enum’s “declaredClass” allows remote attackers to access the ClassLoader and execute arbitrary code. The same issue exists with PropertyUtilsBean.getNestedProperty().
18) Heap-based buffer overflow (CVE-ID: CVE-2025-32415)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the xmlSchemaIDCFillNodeTables() function. A remote attacker can pass specially crafted XML data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
19) 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.
20) Buffer overflow (CVE-ID: CVE-2025-6965)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing aggregated terms. A remote attacker can pass specially crafted input to the application where the number of aggregate terms exceeds the number of columns available, trigger memory corruption and perform a denial of service (DoS) attack.
