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

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, 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: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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: None: There is no loss of confidentiality within the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 14 Jan 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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 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

Restrict network access to the Virtuoso OpenSource database instance by implementing firewall rules or network segmentation to limit exposure to trusted hosts only.
Monitor database logs and network traffic for unusual or malformed SQL queries targeting the sqlo_df component.
Employ query whitelisting or input validation mechanisms where possible to detect and block suspicious SQL statements.
Keep abreast of vendor advisories from OpenLink for patches or official workarounds and apply them promptly once available.
Consider deploying rate limiting or connection throttling to reduce the risk of resource exhaustion from repeated malicious queries.
If feasible, run Virtuoso OpenSource instances behind application-layer proxies or gateways that can filter and sanitize incoming requests.
Regularly back up critical data and have incident response plans ready to restore service quickly in case of a successful DoS attack.
Evaluate the necessity of exposing the database directly to the internet and disable or restrict remote access where not required.

Description

An issue in the sqlo_df component of openlink virtuoso-opensource v7.2.11 allows attackers to cause a Denial of Service (DoS) via crafted SQL statements.

Impact

The primary impact of CVE-2024-57661 is a Denial of Service condition that can disrupt database availability, potentially causing downtime for applications and services dependent on Virtuoso OpenSource 7.2.11. This can affect business continuity, especially for organizations relying on real-time data access or linked data queries. Since the vulnerability does not affect confidentiality or integrity, data theft or manipulation is not a direct concern. However, service outages can lead to operational delays, loss of productivity, and reputational damage. The ease of exploitation (no authentication or user interaction required) and network accessibility increase the risk of attack, especially in environments where the database is exposed to untrusted networks. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once details become widely known. Organizations with critical infrastructure, government data, or commercial linked data services using Virtuoso OpenSource are particularly vulnerable to disruption.

CWE-404Improper Resource Shutdown or Release (opens in a new tab)
Class weaknessLikelihood of exploit: Medium
The product does not release or incorrectly releases a resource before it is made available for re-use.
Requirements · Language Selection
Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation
It is good practice to be responsible for freeing all resources you allocate and to be consistent with how and where you free memory in a function. If you allocate memory that you intend to free upon completion of the function, you must be sure to free the memory at all exit points for that function including error…
Implementation
Memory should be allocated/freed using matching functions such as malloc/free, new/delete, and new[]/delete[].
