CVE-2024-22515 is a high-severity vulnerability classified as an Unrestricted File Upload flaw (CWE-434) found in the iSpyConnect.com Agent DVR software version 5.1.6.0. This vulnerability allows an attacker with limited privileges (requires low privileges, PR:L) but no user interaction (UI:N) to upload arbitrary files through the audio upload component of the application. The vulnerability is remotely exploitable over the network (AV:N) without any authentication barriers, which significantly increases the attack surface. Successful exploitation can lead to complete compromise of the affected system, as the attacker can upload malicious files such as web shells or executables that could be executed on the server, resulting in full confidentiality, integrity, and availability impact (C:H/I:H/A:H). The vulnerability is rated with a CVSS 3.1 score of 8.8, indicating a high risk. Although no known exploits are currently reported in the wild, the nature of the vulnerability and the ease of exploitation make it a critical concern for organizations using this software. The lack of available patches or vendor advisories at the time of publication further exacerbates the risk. The vulnerability specifically targets the audio upload functionality, which may be a less scrutinized attack vector, allowing attackers to bypass typical file upload restrictions or validations.

For European organizations, the impact of CVE-2024-22515 can be severe, especially for those relying on Agent DVR for video surveillance and monitoring. Compromise of these systems could lead to unauthorized access to sensitive video feeds, breach of privacy regulations such as GDPR, and potential disruption of security operations. Attackers could leverage the vulnerability to deploy ransomware, steal confidential data, or use the compromised system as a foothold for lateral movement within the network. The high integrity and availability impact means critical security infrastructure could be disabled or manipulated, undermining physical security and safety. Additionally, the breach of video surveillance systems can have legal and reputational consequences, particularly in sectors like transportation, public safety, healthcare, and critical infrastructure, which are prevalent across Europe. The vulnerability's network accessibility and lack of required user interaction increase the likelihood of automated exploitation attempts, raising the urgency for European entities to address this threat promptly.

To mitigate CVE-2024-22515, European organizations should immediately audit their use of Agent DVR software and identify any instances of version 5.1.6.0 or earlier. Since no official patches are currently available, organizations should implement compensating controls such as restricting network access to the Agent DVR management interfaces via firewalls or VPNs, limiting exposure to trusted internal networks only. Employ strict file upload filtering and validation at network perimeters or proxy layers to detect and block malicious payloads targeting the audio upload component. Monitor logs for unusual upload activity or file types inconsistent with normal operations. Disable or restrict the audio upload feature if it is not essential to business operations. Organizations should also prepare for rapid patch deployment once a vendor fix is released and consider deploying intrusion detection/prevention systems (IDS/IPS) signatures tailored to detect exploitation attempts of this vulnerability. Regularly update and harden the underlying operating system and application environment to reduce the attack surface. Finally, conduct security awareness training for administrators to recognize signs of compromise related to this vulnerability.
