CVE-2024-48248
Published: 04 March 2025
Summary
CVE-2024-48248 is a high-severity Absolute Path Traversal (CWE-36) vulnerability in Nakivo Backup \& Replication Director. Its CVSS base score is 8.6 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
NAKIVO Backup & Replication versions prior to 11.0.0.88174 contain an absolute path traversal flaw in the getImageByPath endpoint exposed at /c/router. The issue stems from insufficient input validation that permits attackers to supply arbitrary filesystem paths, exposing any readable file on the host, including configuration data that stores cleartext credentials for PhysicalDiscovery components.
Remote unauthenticated attackers can exploit the traversal over the network to retrieve sensitive files. Because the recovered credentials often belong to discovery services that span multiple systems, successful file reads can enable lateral movement and remote code execution across an enterprise backup environment.
Vendor release notes confirm the defect is resolved in 11.0.0.88174, and CISA has added the CVE to its Known Exploited Vulnerabilities catalog. Public proof-of-concept code and detailed analysis from WatchTowr Labs are also available, underscoring the need for immediate patching.
The EPSS score has reached 0.94, indicating substantial real-world exploitation interest.

Vulnerability details
NAKIVO Backup & Replication before 11.0.0.88174 allows absolute path traversal for reading files via getImageByPath to /c/router (this may lead to remote code execution across the enterprise because PhysicalDiscovery has cleartext credentials).

Why these techniques?
Unauthenticated path traversal enables arbitrary file read (T1190: Exploit Public-Facing Application), including cleartext credentials in PhysicalDiscovery files (T1552.001: Credentials In Files), facilitating credential access via exploitation (T1212: Exploitation for Credential Access).
