Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Adjacent: The vulnerable component is bound to the network stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared physical (e.g., Bluetooth or IEEE 802.11) or logical (e.g., local IP subnet) network, or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN to an administrative network zone).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

If you cannot patch yet, network segmentation should be enforced to restrict access to the SPS RDP component, limiting exposure to trusted networks only. Deploy strong network-level encryption such as VPNs or IPsec tunnels to protect RDP traffic from interception. Implement strict monitoring and anomaly detection on privileged session activities to identify potential unauthorized access attempts. Employ multi-factor authentication (MFA) for administrative access where possible to add an additional layer of security. Regularly audit and review privileged session logs for suspicious behavior. Additionally, consider disabling or restricting RDP access if not essential, or replacing it with more secure remote access technologies. Engage with One Identity support for guidance and early access to patches or workarounds. Finally, educate security teams about the risks of cleartext transmission vulnerabilities and the importance of securing privileged session management tools.

Description

An authentication-bypass issue in the RDP component of One Identity Safeguard for Privileged Sessions (SPS) On Premise before 7.5.1 (and LTS before 7.0.5.1) allows man-in-the-middle attackers to obtain access to privileged sessions on target resources by intercepting cleartext RDP protocol information.

Impact

The primary impact of CVE-2024-40595 is unauthorized access to privileged sessions managed by One Identity Safeguard for Privileged Sessions. Successful exploitation allows attackers to bypass authentication by intercepting cleartext RDP data, potentially leading to exposure of sensitive administrative credentials and session information. This can result in unauthorized administrative actions, data exposure, and lateral movement within enterprise networks. The confidentiality of privileged sessions is severely compromised, although integrity and availability are not directly affected. Organizations relying on One Identity SPS for privileged access management face increased risk of insider threats and external attackers gaining elevated access. The medium CVSS score reflects the requirement for network proximity and high attack complexity, limiting widespread exploitation but still posing a significant threat to targeted environments. The absence of known exploits in the wild suggests limited current exploitation but does not preclude future attacks. Overall, the vulnerability threatens the security of critical infrastructure and sensitive enterprise systems where privileged session management is essential.

CWE-319Cleartext Transmission of Sensitive Information (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A04:2025: Cryptographic Failures (opens in a new tab)
The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.
Architecture and Design
Before transmitting, encrypt the data using reliable, confidentiality-protecting cryptographic protocols.
Implementation
When using web applications with SSL, use SSL for the entire session from login to logout, not just for the initial login page.
Implementation
When designing hardware platforms, ensure that approved encryption algorithms (such as those recommended by NIST) protect paths from security critical data to trusted user applications.
