Lifecycle Timeline
3DescriptionCVE.org
A weakness has been identified in Tenda AC15 15.03.05.19. The impacted element is an unknown function of the file /etc_ro/smb.conf of the component Samba. Executing a manipulation can lead to weak password requirements. The attack is only possible within the local network. A high complexity level is associated with this attack. The exploitability is regarded as difficult. The exploit has been made available to the public and could be used for attacks.
AnalysisAI
Weak password requirements in the Samba service of Tenda AC15 firmware 15.03.05.19 expose SMB file-sharing functionality to brute-force attacks from adjacent-network attackers. The flaw originates in the /etc_ro/smb.conf configuration, which enforces insufficient password complexity, enabling unauthenticated local-network adversaries to guess or brute-force credentials and achieve limited confidentiality, integrity, and availability impact. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to be positioned on the same adjacent network (LAN or WLAN) as the vulnerable Tenda AC15 - remote internet-based exploitation is not possible per AV:A. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.0 score reflects a bounded but real threat: AV:A limits exploitation to the local network segment, and AC:H signals that exploitation requires non-trivial conditions or precise targeting, reducing opportunistic risk significantly. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker physically present on the same local network segment as the Tenda AC15 router - such as a guest on a home or small-office Wi-Fi network - discovers the active Samba file-sharing service and leverages the weak password policy to brute-force SMB credentials using the publicly available proof-of-concept. With valid credentials obtained, the attacker accesses shared files on storage attached to the router, potentially exfiltrating sensitive documents or staging further lateral movement against other LAN-connected systems. … |
| Remediation | No vendor-released patch has been identified at time of analysis for this vulnerability. … Detailed patch versions, workarounds, and compensating controls in full report. |
