Overview<\/strong><\/p>\n

CVE-2025-49480 is a significant vulnerability associated with the ASR180x and ASR190x in lte-telephony. This out-of-bounds access flaw affects Falcon_Linux, Kestrel, and Lapwing_Linux, versions prior to v1536, potentially compromising system integrity or leading to data leakage. The severity of this vulnerability underscores the importance of prompt patch application and diligent system monitoring.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-49480
\nSeverity: High (7.4 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: System compromise, potential data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Falcon_Linux | Before v1536
\nKestrel | Before v1536
\nLapwing_Linux | Before v1536<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The vulnerability stems from an out-of-bounds access issue in the ASR180x and ASR190x software in lte-telephony. Specifically, the flaw is located within the apps\/lzma\/src\/LzmaEnc.c file, where improper validation of user-supplied input leads to out-of-bounds read\/write conditions. An attacker can exploit this vulnerability to execute arbitrary code within the context of the application, leading to system compromise or potential data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

While no specific exploit code is available, a conceptual example might involve an attacker sending a network request with manipulated data designed to trigger the vulnerability. A hypothetical example might look like this:<\/p>\n

POST \/lte-telephony\/ASR180x\/endpoint HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"manipulated_data\": \"long_string_that_triggers_out_of_bounds_access\" }<\/code><\/pre>\n
This hypothetical request could cause the application to access data outside of its intended bounds, potentially leading to system compromise or data leakage.<\/p>\n","protected":false},"excerpt":{"rendered":"
