Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Improper access control (CVE-ID: CVE-2014-0107)
The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to TransformerFactory in Apache Xalan-Java does not properly restrict access to certain properties when FEATURE_SECURE_PROCESSING is enabled. A remote attacker can bypass implemented security restrictions and load arbitrary classes or access external resources via a crafted (1) xalan:content-header, (2) xalan:entities, (3) xslt:content-header, or (4) xslt:entities property, or a Java property that is bound to the XSLT 1.0 system-property function.
2) Improper input validation (CVE-ID: CVE-2022-34169)
The vulnerability allows a remote non-authenticated attacker to compromise the affected system.
The vulnerability exists due to an integer truncation issue when processing malicious XSLT stylesheets. A remote non-authenticated attacker can pass specially crafted data to the application to corrupt Java class files generated by the internal XSLTC compiler and execute arbitrary Java bytecode.
3) UNIX symbolic link following (CVE-ID: CVE-2013-0248)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue. The application uses the /tmp directory for uploaded files. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
4) Resource exhaustion (CVE-ID: CVE-2016-3092)
The vulnerability allows a remote attacker to cause denial of service conditions on the target system.The vulnerability exists due to input validation error when processing very long boundary strings within the MultipartStream class in Apache Commons Fileupload. A remote user can cause denial of service conditions by sending specially crafted boundary string and consume excessive CPU resources.
Successful exploitation of this vulnerability may result in denial of service attack.
5) Desereliazation of untrusted data (CVE-ID: CVE-2016-1000031)
The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.The weakness exists in DiskFileItem class of the FileUpload library due to deserialization of untrusted data. A remote attacker can execute arbitrary code under the context of the current process.
Successful exploitation of the vulnerability may result in system compromise.
6) Infinite loop (CVE-ID: CVE-2014-0050)
The vulnerability allows a remote attacker to cause DoS conditions on the target system.The weakness exists due to boundary error when handling Content-Type HTTP header for multipart requests. By sending a specially crafted Content-Type header, containing 4092 characters in "boundary" field, a remote attacker can cause the application to enter into an infinite loop.
Successful exploitation of the vulnerability results in denial of service on the vulnerable system.
Note: the vulnerability was being actively exploited.
7) Input validation error (CVE-ID: CVE-2013-2186)
The vulnerability allows a remote attacker to overwrite arbitrary files on the system.
The vulnerability exists due to insufficient validation of user-supplied input when processing file names with a NULL byte within the DiskFileItem class. A remote attacker can upload a specially crafted file with a NULL byte in its name and overwrite arbitrary files on the system.
8) Improper Certificate Validation (CVE-ID: CVE-2012-5783)
The vulnerability allows a remote attacker to perform a man-in-the-middle attack to spoof SSL servers via an arbitrary valid certificate.
The vulnerability exists due to Apache Commons HttpClient does not verify that the server hostname matches a domain name in the subject's Common Name (CN) or subjectAltName field of the X.509 certificate. A remote attacker can perform a man-in-the-middle attack to spoof SSL servers via an arbitrary valid certificate.
9) Path traversal (CVE-ID: CVE-2021-29425)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error within the FileNameUtils.normalize method when processing directory traversal sequences, such as "//../foo", or "\..foo". A remote attacker can send a specially crafted request and verify files availability in the parent folder.
10) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2023-24998)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to Apache Commons FileUpload does not limit the number of request parts. A remote attacker can initiate a series of uploads and perform a denial of service (DoS) attack.
