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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

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 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), or CISA SSVC or the CVSS exploit maturity 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.

AI-suggested

Immediate mitigation involves isolating affected devices from untrusted networks to reduce exposure.
Monitor network traffic for anomalous session cookie usage or unauthorized access attempts.
Contact the vendor for firmware updates that replace MD5 with a secure hash function and improve session token generation; prioritize applying these updates once available.
If firmware updates are unavailable, consider deploying compensating controls such as network segmentation, strict access control lists, and VPNs to restrict management interface access.
Implement multi-factor authentication (MFA) on device management interfaces if supported, to add an additional layer of security beyond session tokens.
Regularly audit device logs for suspicious activity indicative of session forgery attempts.
Educate network administrators about the risks of weak cryptographic functions and encourage migration to devices with modern security standards.
Develop incident response plans that include this vulnerability scenario to quickly contain potential breaches.

Description

SODOLA SL902-SWTGW124AS firmware versions through 200.1.20 use the cryptographically broken MD5 hash function for session cookie generation, weakening session security. Attackers can exploit predictable session tokens combined with MD5's collision vulnerabilities to forge valid session cookies and gain unauthorized access to the device.

Impact

The primary impact of this vulnerability is unauthorized access to the affected device due to session cookie forgery. Attackers can bypass authentication mechanisms, potentially gaining administrative control or access to sensitive device functions. This compromises confidentiality and integrity of device management sessions, enabling further attacks such as network reconnaissance, configuration changes, or pivoting within the network. While availability is not directly impacted, unauthorized control could lead to denial-of-service or disruption if attackers manipulate device settings. Organizations relying on these devices for network gateway or security functions face increased risk of compromise, data leakage, and lateral movement by attackers. The lack of required privileges or user interaction makes exploitation easier, increasing the threat surface. The absence of known exploits suggests limited current impact but also highlights the need for proactive mitigation before attackers develop weaponized exploits. Overall, the vulnerability poses a moderate risk to organizations using the affected devices, especially in critical infrastructure or sensitive environments.

CWE-328Use of Weak Hash (opens in a new tab)
Base weaknessOWASP Top 10 A04:2025: Cryptographic Failures (opens in a new tab)
The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack).
Architecture and Design
Use an adaptive hash function that can be configured to change the amount of computational effort needed to compute the hash, such as the number of iterations ("stretching") or the amount of memory required. Some hash functions perform salting automatically.
