Threat metrics

Exploit Maturity: POC

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: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 18 Jul 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 2026-10-26.

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.

AI-suggested

To mitigate CVE-2025-7797, European organizations should prioritize the following actions: 1) Immediately apply the official patch identified by commit 153ea314b6b053db17164f8bc3c7e1e460938eaa to all affected GPAC versions (2.0 through 2.4). 2) Conduct an inventory to identify all systems and applications using GPAC, including embedded devices and third-party software that may bundle GPAC components. 3) Implement network-level protections such as web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block malformed requests targeting the vulnerable function, especially if patching cannot be immediately applied. 4) Monitor logs and network traffic for unusual patterns or crashes related to media streaming services. 5) Establish robust incident response procedures to quickly isolate and remediate affected systems in case of exploitation. 6) Engage with software vendors and service providers to confirm patch deployment and assess exposure. 7) Consider deploying runtime application self-protection (RASP) or sandboxing techniques for media processing components to limit the impact of potential crashes. These steps go beyond generic advice by focusing on comprehensive asset identification, layered defenses, and proactive monitoring tailored to the nature of the vulnerability.

Description

A vulnerability was found in GPAC up to 2.4. It has been rated as problematic. Affected by this issue is the function gf_dash_download_init_segment of the file src/media_tools/dash_client.c. The manipulation of the argument base_init_url leads to null pointer dereference. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The patch is identified as 153ea314b6b053db17164f8bc3c7e1e460938eaa. It is recommended to apply a patch to fix this issue.

Impact

For European organizations, the impact of CVE-2025-7797 primarily involves potential service disruptions in multimedia applications or services that rely on the GPAC framework for DASH (Dynamic Adaptive Streaming over HTTP) content delivery. This could affect media streaming platforms, content delivery networks, or any enterprise systems integrating GPAC for media processing. A successful exploitation could lead to denial of service, causing downtime or degraded user experience. While the vulnerability does not directly compromise data confidentiality or integrity, availability issues can have significant operational and reputational consequences, especially for media companies, broadcasters, and enterprises providing streaming services. Additionally, denial of service conditions could be leveraged as part of broader multi-vector attacks or to distract from other malicious activities. Organizations with automated or large-scale media processing pipelines may experience cascading failures if the vulnerability is exploited at scale.
