CVE-2015-4068 is classified as a critical directory traversal vulnerability affecting Arcserve Unified Data Protection (UDP) prior to version 5.0 Update 4. This vulnerability allows remote attackers to obtain sensitive information or cause a denial of service by sending a crafted file path to specific servlets, namely the reportFileServlet and exportServlet. The critical nature of this vulnerability is underscored by its CVSS score of 9.1, indicating severe potential impacts on confidentiality and availability.
Risk to organizations includes unauthorized access to sensitive data and potential disruptions in service. Given the ease of exploitation and the lack of required privileges, this vulnerability poses a significant threat. Organizations running affected versions of Arcserve UDP must prioritize patching to mitigate the risks associated with CVE-2015-4068.
As of now, there are no known public exploits or proof-of-concept code available in the wild. However, the vulnerability is listed in the Known Exploited Vulnerabilities (KEV) catalog, indicating its significance and the likelihood of exploitation in active attack scenarios. Organizations should address this vulnerability immediately to prevent potential breaches.
Organizations should prioritize patching immediately. The urgency of this situation cannot be overstated, as attackers may leverage this vulnerability to compromise sensitive information or disrupt services.
Vulnerability Details
The CVE description indicates that the vulnerability is due to inadequate validation of user-supplied file paths in the affected servlets. The CVSS score of 9.1 indicates that the vulnerability is a critical risk, primarily due to its high confidentiality impact and availability impact. Arcserve UDP versions prior to 5.0 Update 4 are affected by this vulnerability, which was published on May 29, 2015.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of file path inputs in the servlets. Attackers can exploit this flaw to perform directory traversal attacks, which would allow them to access files outside the intended directory structure. The attack vector is through network interactions, with low complexity and no required privileges. Additionally, user interaction is not necessary for the attack to succeed. The impact on confidentiality is high, as sensitive data can be exposed, while availability can also be compromised through denial of service.
Risk & Impact Analysis
The real-world risk associated with CVE-2015-4068 includes potential exposure of sensitive information and system unavailability. The blast radius could be significant, especially for organizations relying on Arcserve UDP for data protection. Given the critical severity of this vulnerability, organizations should assess their exposure and prioritize remediation efforts in their patch management cycle. The urgency is underscored by its inclusion in the KEV catalog, which highlights its active exploitation potential.
